Description

Пример 1. Получение 2-фенилимидазо 4,5-с пиридина (соединение № 1).Example 1. The preparation of 2-phenylimidazo 4,5-c pyridine (compound No. 1).

Смесь, состо вшую из эквимолекул рных количеств 3,4-диаминопиридина, бензальдегида и серы, нагревают 4 ч ири 170-175°С, охлаждают до комнатной темиературы и продукт реакции кристаллизуют из водного спирта. Т. пл. 227°С. Выход 91%.A mixture consisting of equimolecular amounts of 3,4-diaminopyridine, benzaldehyde and sulfur is heated for 4 hours with 170-175 ° C, cooled to room temperature and the reaction product is crystallized from aqueous alcohol. T. pl. 227 ° C. Yield 91%.

В случае проведени  реакции в растворителе (мезитилен) на 1 вес. ч. серы берут 25 вес. ч. мезитилена. Реакцию провод т при температуре кипепи  реакционной массы 2-4 ч. Осадок после охлаждени  отфильтровывают и очищают кристаллизацией.If the reaction is carried out in a solvent (mesitylene) by 1 weight. h. sulfur take 25 weight. h. mesitylene. The reaction is carried out at the boiling point of the reaction mass for 2-4 hours. After cooling, the precipitate is filtered off and purified by crystallization.

Аналогично примеру 1 с использованием соответствующих исходных продуктов при нагревании в течение 1-6 ч при 150-175°С получены следующие целевые соединени :Analogously to Example 1, using the corresponding starting materials, the following target compounds were obtained by heating for 1-6 hours at 150-175 ° C:

№22- (4 - диметиламинофенил) -имидазо 4,5-с пиридип;No. 22- (4 - dimethylaminophenyl) -imidazo 4,5-c pyridip;

№ 3 2 - (4-метоксифенил)-имидазо 4,5-с пиридин;No. 3 2- (4-methoxyphenyl) -imidazo 4,5-c pyridine;

№ 4 1 - метил-2-(1-метилиндолил-2)-имидазо 4 ,5-Ь пиридип;No. 4 1 - methyl-2- (1-methylindolyl-2) -imidazo 4, 5-b pyridip;

№ 5 2 - фенилимидазо 4,5-Ь пиридип;No. 5 2 - phenylimidazo 4,5-b pyridip;

№ 6 2 - 4-(диметиламино)-фенил -5-хлоримидазо 4,5-& пиридин.No. 6 2 - 4- (dimethylamino) -phenyl-5-chlorimidazo 4,5- & pyridine.
