The invention can find application in pharmacology and for new photoluminescent products.

A method of obtaining 4(5)-phenylimidazole (Bredereck, H., F. Effenberger, Marquez F.e.a. // Chem. Ber. 1960. Bd.93. s. 2083).

A mixture of 8 g (0.04 mol) of pencilvania and 50 ml of formamide is boiled in a flask with a return air refrigerator 2 hours After cooling, it is treated with 200 ml of hot diluted hydrochloric acid (1:1), if necessary, boiled with charcoal, filtered and the filtrate is alkalinized with ammonia solution to pH 7-8. Fallen 4(5)-phenylimidazole separate and purify successive recrystallization from water and benzene, receiving colorless plates with TPL=128-129°C.

Unfortunately, this method is unsuitable for obtaining 4(5)-(2-hetaryl)imidazoles as boiling in the environment of formamide is the resinification of the original connections.

The closest is a method of obtaining 4(5)-(2-furyl)imidazole (Schubert H., E. Haden, Lehman G. of α-furyl-imidazole and Furfurin // Joumal fur Praktische Chemie 1962. Bd.17. S.173 - 179).

2-Bromoacetophenone: 65 g (0.5 mmol) furoyl-2-chloride with good stirring, slowly add the ethereal solution diazomethane (2 l sod. ~ 1.2 mol). After 2 h, stirred with 40% HBr. Then the ether solution is double-distilled in vacuum. Get 33 g (35%) of a colorless oil with TKip=115-120°C (14 mmHg).

4(5)-(2-Furyl)imidazole: 19 g (0.1 mol) of bracelona in 100 ml of methanol is heated for 2 hours with 15 g of potassium acetate. Then CVG separated and the methanol to the solution carmenelectra added with stirring a solution of 100 g of copper acetate, 60 ml of formalin and 1200 ml conc. solution of NH3and slowly heated. From the reaction mass in this fall 30 g (40%) copper salt. It is suspended in 500 ml of water and passed through a suspension of H2S. Separate CuS, and from the filtrate falls crude imidazole, which is recrystallized from water with activated carbon. Get colorless crystals with TPL=118-119°C.

However, this method is not very common, long time, has a higher cost, environmentally unsafe and has no advantages in comparison with the proposed terms of constructability and purity.

The objective of the invention is the expansion of the range of target products while simplifying and environmental purification process of getting known and new (5)-(2-hetaryl) and 4(5)-(2-hetaryl)-2-(2'-hetaryl)-imidazoles.

The problem is solved so that 4(5)-(2-hetaryl) and 4(5)-(2-hetaryl)-2-(2'-hetaryl)-imidazoles of General formula:

R=2-furyl, 2-thienyl; R'=H; R=2-furyl, 2-thienyl; R'=2-furyl, 2-thienyl unlike structural analogue is obtained using 2-bromoacetophenone (thiophene) General formula:

X=O,S

and aldehydes in the presence of copper sulfate, the synthesis of the precursor of 2-bromo-ACE-is infurna (thiophene) is realized by the interaction of 2-acetylfuran (thiophene) not difficult and explosive diazomethane, and with cheap and stable copper bromide (II).

These conditions greatly increase the security of the process due to the fact that previously, to obtain 2-bromoacetophenone used explosive and hard-diazomethane (Schubert H., E. Haden, Lehman G. of α-furyl-imidazole and Furfurin // Joumal fur Praktische Chemie, 1962. Bd.17. S.173-179.)

Example. Getting 4(5)-(2-hetaryl) and 4(5)-(2-hetaryl)-2-(2'-hetaryl)-imidazoles (General method)

Suspended 0.11 mol CuBr2in 100 ml of ethyl acetate, boiling and stirring, treated with a solution of 0.1 mol of 2-acetylfuran (thiophene) in 100 ml of chloroform. The mixture is then boiled for 6 h, after which separate CuBr, distilled solvent mixture, and the residue is used without further purification. To a solution of 0.07 mol of potassium acetate in 100 ml of methanol is poured 0.05 mol of 2-bromoacetophenone (thiophene) and under stirring with a magnetic stirrer boiled for 2 hours Then filtered CVG, and the filtrate is introduced into a solution containing 0.5 mol (CH3COO)2Cu·H2O in 1200 ml of 25%aqueous NH4OH and 60 ml of 37%formalin (or an equivalent amount of furfural, benzaldehyde or 2-tiefenanzeige). The mixture is boiled for 1.5 h, then separated copper salt, suspended it in 10 ml of water and is decomposed by a current of hydrogen sulphide within 0.5 hours the resulting solution was acidified with conc. the model HC1 solution and separate the CuS. When the alkalization of the filtrate to a 25%solution of ammonia saliva target is the product, which is separated and dried in the air.

The proposed method allows to synthesize compounds with biological activity. So, for example, iodide, 1,3-dimethyl-5-bromo-2-(5'-2'-furyl)midsole possesses fungicidal activity (Grebennikov, VA, etc. // ABT. mon. No. 1542010, 1989), and 2-(5'-nitro-2-furyl)imidazole bacteriostatic activity (Stoyanov, V.M. and others// ABT. mon. No. 1032755,1983). In addition, they are synthons for obtaining a large series of products with antifungal and antibacterial activity (Elchaninov M.M. and other // ABT. mon. No. 1032755, 1983) and phosphors.
