The new compound of the formula I can be obtained using the reactions and techniques described in this section. These reactions are conducted in the environment of a solvent suitable for the used reagents and substances, namely, suitable for implementation of the necessary chemical reactions. Specialists in the field of organic synthesis well known that functionality, "carried" by imidazole and other parts of the molecule compounds must comply with the proposed chemical transformations. As well as in the implementation via unprotect, methods of activating position in the ring of the benzyl able to "stitch" with nitrogen in the imidazole nucleus. Not all compounds of formula I, referred to in the text of this section and attributable to a specific class, you can get all the methods described for this class. Replaced the group's original substances may not be compatible with certain reaction conditions that are required in the case of some of the mentioned methods. The limitation imposed on the replaced group in respect of their compatibility with the reaction conditions, it is obvious for one of the alternative methods described in this section.Basically proposed connection easy to get direct alkylation of imidazole is protected adequately by benzylchloride, tosylate or mesilate in the presence of a base. Better if you get salt imidazole reaction of imidazole I with a proton acceptor, such as MN, where M is lithium, sodium or potassium, in a solvent such as dimethylformamide (DMF), or by conducting the reaction of the imidazole of formula I with a metal alkoxide of the formula MOR, where R is methyl, ethyl, tert-butyl alcohol solvent (ethanol or tert-butyl alcohol), or in the dipolar proton the com as DMF, and the above process almyroudis agent. In another case, the imidazole can be alkilirovanii antilogarithm (bromide or chloride) in the presence of a base such as sodium carbonate, potassium carbonate, triethylamine or pyridine. The reaction is carried out in an inert solvent, such as DMF or dimethylsulfoxide (DMSO) at temperatures between 20oWith temperatures of distillation of the solvent for 1 to 10 hoursPreferred ways of getting tetrazolo shown in scheme 1 by equations a and b.

Required azides trialkyl or triarylamine synthesized from the commercially available chloride trialkyl and tiarella and sodium azide. The group trialkyl or Triaryl-tin remove acidic or basic hydrolysis, and tetrazol you can protect a group of trityl carrying out the reaction with Fritillaria and triethylamine getting connection With. Subsequent bromination with N-bromosuccinimide and dibenzofuran the tvii Foundation, with the subsequent removal of the protecting group of trityl by hydrolysis gives compound 1, in which R tetrazol. To protect tetrazoles part of the molecule instead of a group of trityl you can use other protective groups, such as para-nitrobenzyl and I-ethoxyethyl. These groups, as well as a group of trityl, can be inserted and removed according to the methods described in Greene, "Protective groups in organic synthesis" (Green, Protective Groups in Organic Synthesis, Wiley Interscience, 1980) (see scheme 1).The compounds of formula I, where R2arylalkyl, and R3represents CH2OH, Cho, or COOH, can be obtained as shown in scheme 2.2-alkylimidazole-4,5-dicarboxylic acid And obtained by the method, which was developed Farger and Pimen (Farger R.
