Disclosed heterocycle-cyclic derivatives of amines of the formula I, where X, M, L, R1, R2, R7, R8presented on pages 121-124 descriptions, or their salts, intermediate compounds, pharmaceutical composition and method of inhibiting cholinesterase-based compounds of the formula I, the method of obtaining these compounds. 6 C. and 4 h.p. f-crystals, 1 table.

The present invention relates to heterocycle-cyclic amine derivative of the formula I and their pharmaceutically acceptable salts. The compounds of formula I are inhibitors of cholinesterase and can be used to improve memory in patients with dementia and Alzheimer's.

Alzheimer's disease is caused by degeneration of cholinergic neurons in the basal fore brain, which play a fundamental role in the cognitive brain, including memory. See, Becker and others, Drug Development Research, 12, 163-195 (1988). As a result of this degeneration, patients suffering from the disease, reveals a noticeable reduction in the synthesis of acetylcholine, cholineacetyltransferase linestart are an effective means to increase cholinergic activity and can be used to improve memory in patients suffering from Alzheimer's disease. By inhibiting acetylcholinesterase these compounds contribute to the high levels of the neurotransmitter acetylcholine in the brain and thus help to improve memory. In the above-mentioned work of Becker and others indicate that behavioral changes after inhibition of cholinesterase, obviously, correspond to predicted peak levels of acetylcholine in the brain. In this work also discusses the effectiveness of three known acetylcholinesterase inhibitors, namely physostigmine, metrifonate and tetrahydroaminoacridine.

Detailed description of the invention

Obtaining compounds of formula I and some of the source materials used for the synthesis of these compounds, pollastri the R2, R3, R4, R5, R6, R7, R8, R13, R14, E, G, X, Y, M, L, a, b, I, m, n, p and structure I, A, B, and K are the same as defined above, if it is not specifically mentioned.

All articles, monographs, patents, and patent applications cited in the following discussion, introduced in the present description by reference. Scheme 1 - 6 listed at the end of the text.

Obtaining compounds of formula I in which Y is -(CH2)mand M is-CH-, illustrated in figure 1. These connections are depicted in figure 1 and designated as compounds of formula I-A (where L represents a phenyl-(C1-C6)-alkyl, pyridylmethyl or a group of formula (K) and as the compounds of formula I-B (where a represents a phenyl or cinnamyl).

In scheme 1 the compounds of formula I-A can be obtained by deprotonation of compounds of formula II using a base in the presence of or followed by addition of an alkylating agent of the formula III, where R10represents azatadine group, and W represents a leaving group. If R10is asutamisega group, this reaction produces an intermediate compound of formula IV. This intermediate with the warping or salt of the free base, then the specified free base or its salt alkylate using the compounds of formula WL, where W is defined above, and L represents phenyl(C1-C6)-alkyl, pyridylmethyl or a group of the formula K.

Examples of suitable leaving groups (W) are mesilate, tosylate, chloride, iodide or bromide. Examples of suitable azatadine groups (R10are amides, such as N-formyl and N-acetyl, and carbamates such as t-butoxycarbonyl (VOS). Preferred azatadine groups are VOS. Suitable bases used to produce compounds of formula IV are strong bases, such as diisopropylamide lithium (LDA), n-utility, s-utility, and hexamethyldisilazide lithium or sodium, or potassium (LiHMDS, NaHMDS or KHMDS). Preferred are LDA and s-utility.

The reaction of the compound of formula II with the compound of the formula III in the main, carried out in a polar aprotic solvent such as diethyl ether, 1,2-dimethoxyethane or tetrahydrofuran (THF). The reaction temperature can vary from about -70 to about 30oC. Preferably, if the above reaction is carried out in THF at about -70oC.

Basically, the compounds of formula II is subjected to the depot is on proton acid, it is preferable to first carry out phase deprotonation and subsequent immediate and rapid addition of an alkylating agent of the formula III.

Protective group (R10) can be removed from compounds of formula IV with the formation of the corresponding compounds of formula VI by conventional methods well known in the art. For example, if R10is the SUN or other carbamato, this group can be removed using acids, such as bromovalerate (gaseous or liquid), hydrogen chloride (gaseous or liquid) or triperoxonane acid. In the case of triperoxonane acid may be added to the acceptor t-butyl cations, such as thioanisole. If razblokirovka agent acid is used, the result will be produced not free base of compounds of formula VI and its acid additive salt. Suitable solvents are non-polar solvents, such as methylene chloride, and also polar solvents, such as diethyl ether, ethyl acetate, dioxane, alcohols, such as methanol or ethanol, and water. Temperatures can vary from about -20oC and arr. to the temperature of distillation. Predpochtite the Colo 0oC.

Alternatively, if R10is VOS, it can be removed using triallylisocyanurate derivative, such as (trimethylsilyl) -, triethylsilyl - or t-butyldimethylsilyl-triftorbyenzola, in the presence of aromatic or tertiary amine base, such as 2,6-lutidine or triethylamine. Suitable solvents for this reaction are non-polar solvents, such as methylene chloride, and polar solvents such as THF, diethyl ether or DMF. Temperatures can vary from about -20oC to room temperature. For this reaction it is preferable to use trimethylsilyltrifluoromethane-sulfonate and 2,6-lutidine in methylene chloride at a temperature of from about 0oC and approximately to room temperature.

Intermediate secondary piperidine of the formula VI obtained in the form of free base or salt, as described above, is subjected to reaction with 2-10 equivalents of the base, and then with an alkylating agent of the formula WL, where W is the group defined above, and L is phenyl-(C1-C6)-alkyl, pyridylmethyl or a group of the formula K. Suitable bases are tretinoinretin; and metal carbonates, such as sodium bicarbonate, or carbonate of sodium, potassium or cesium. If W is chloride, the catalyst may be added iodide (iodide or potassium iodide, Tetra-n-butylamine). Suitable solvents are non-polar solvents, such as methylene chloride, and polar solvents such as dimethylformamide, THF, acetonitrile, acetone, dioxane, and alcohols, such as methanol or ethanol. The alkylation reaction is preferably carried out in the presence of triethylamine in methylene chloride at room temperature or in the presence of sodium carbonate in dimethyl formamide at room temperature.

Alternatively, the intermediate secondary piperidine of formula VI, if it was obtained in the form of a salt after removal of the protective group may be subjected to deprotonation to obtain the free amine by dissolution or suspension in an appropriate solvent (e.g. methylene chloride or etiennette), mixing with aqueous sodium bicarbonate or aqueous sodium hydroxide or potassium and allocate the free amine from the organic layer using standard extraction techniques. Obtained the free amine can be plugged into the sled above, and with 1-2 equivalents of the appropriate base.

Starting materials of formula II can be obtained by methods well known in the art. If X is oxygen, the original 3-methyl-1,2-benzisoxazole can be obtained by methods similar to those described Wunsch and others, Adv. Heterocycl. Chem., 1967, 8, 277; Smalley P. K., Adv. Heterocycl. Chem. 1981, 29, 2, and Thakar, etc., Indian J. Chem. 1977, 15B, 1058. The corresponding b-hydroxyacetophenone can be converted into the corresponding oximes via reaction with hydroxylamine hydrochloride in the presence of an appropriate base, such as potassium hydroxide or sodium, sodium acetate or pyridine, preferably aqueous potassium hydroxide or aqueous sodium acetate, in a polar solvent such as methanol, ethanol or water, and preferably ethanol, at a temperature from about room temperature to about 120oC. Then the reaction is transformed into the corresponding oxiracetam by acetylation with suitable acetylides agent such as acetic anhydride. This reaction can be conducted at temperatures from about room temperature to the temperature of distillation of the solvent. Preferred are temperatures 80-130oC.

Reago of oxiracetam at a temperature of about 125 - 200oC at atmospheric pressure or reduced pressure, for example from about 0.01 mm RT.article (1,33 10-5bar) to about 760 mm RT.article (1,01 bar). The reaction ring closure preferably by heating oxiracetam when the distillation temperature in the appropriate base, such as pyridine, or by heating oxiracetam at a temperature of about 130oC in a polar solvent such as DMF or DMSO (dimethylsulfoxide) in the presence of several equivalents of the appropriate base, such as pyridine or 2,6-lutidine.

Alternatively, the ring closure may be effected directly from the oxime using its reaction with acyl - or sulphonylchloride, such as oxalyl or thionyl chloride, in the presence of an aromatic amine, such as pyridine (see , Kalkote and others, Aust, J. Chem., 1977, 30, 1847). Suitable solvents are polar solvents, such as diethyl ether or THF. Temperatures can vary from about 0oC and approximately to room temperature. Another way to ring closure is the treatment of the oxime one or less equivalents of base, such as potassium hydroxide, in a polar solvent such as methanol, at temperatures in the limit of which is sulfur, the original 3-methyl-1,2-benzisothiazole can be obtained from o-methylthiazolidine in accordance with the procedures described above for benzisoxazole (see, McLinnon and others, Can. J. Chem., 1988, 66, 1405 and works cited in the present description). b-Methylthiazolidine converted into the corresponding oximes and ring closure is carried out directly by reaction with the corresponding allermuir agent such as acetic anhydride in the base, such as pyridine. The reaction temperature may be from about room temperature to about 130oC, and preferably about 120oC.

If R1and R2both are NH2the source material of the formula II can be obtained from the corresponding NHAc-predecessor (Ac=acetyl) using acid hydrolysis. Acid hydrolysis can be carried out using hydrochloric acid at temperatures of from about 50 to about 120oC. However, it is preferable temperatures of distillation (about 120oC) 1 N. HCl. Appropriate connections NHBZ (BZ=benzoyl) or NHSO2C6H5can be obtained from the corresponding amino derivative t is min, pyridine or dimethylaminopyridine. Suitable solvents are methylene chloride, THF, diethyl ether or dimethylformamide. The reaction temperature can be from about -20 to about 80oC. If one or both of R1and R2are NHBZ, it is preferable to use the triethylamine/dimethylaminopyridine in methylene chloride at room temperature. If one or both of R1and R2are NHSO2Ph, it is preferable to use pyridine in methylene chloride at 0oC.

Cyclic dialkylamino-the compounds of formula II (i.e., compounds in which one or both R1and R2are NR5R6where NR5R6together form a ring) can also be obtained from the corresponding amino derivative by alkylation, using the appropriate bis-halide reagent of the formula

The alkylation is usually carried out at temperature is under the base Hunga in toluene at about 120oC (distillation temperature) (see Verboom, etc., J. Org. Chem. 1984, 49, 269).

Alternatively, these cyclic dialkylamino-derivatives can be obtained by nucleophilic substitution of aromatic fluoride appropriate cyclic amine. Suitable for this reaction solvents are polar aprotic solvents such as dimethylsulfoxide (DMSO), dimethylformamide (DMF), acetonitrile, pyridine and hexamethylphosphoramide. Preferred are acetonitrile and pyridine. The reaction may proceed in the presence of a base, such as tertiary or aromatic amines (e.g. triethylamine, diisopropylethylamine, pyridine or dimethylaminopyridine), and preferably pyridine or triethylamine. The reaction can be carried out at a temperature of approximately from room temperature and up to about 160oC, and preferably from about 80 to about 160oC.
