FIELD: chemistry.
SUBSTANCE: invention relates to 4-R derivatives of 4H-bis[1,2,5]-oxadiazolo[3,4-b:3',4'-f]azepine-8,9-diamine of general formula (I), where R denotes H, an NH2 group, an alkyl substitute or a substituted alkyl substitute. The compounds are obtained by reducing 7-R substituted derivatives of tris[1,2,5]oxadiazolo[3,4-b:3',4'-d:3",4"-f]azepine-1-oxide, where R denotes H, an NH2 group, an alkyl substitute or a substituted alkyl substitute, with reducing agents selected from: hydrazine in free form, hydrazine in form of salts of hydrazine and mineral acids, hydrazine in form of salts of hydrazine and organic acids, hydrogen in the presence of a suitable reducing catalyst, known as a hydrogenating catalyst. The 4H-bis[1,2,5]oxadiazolo[3,4-b:3',4'-f]azepine-8,9-diamine derivatives are suitable for synthesis of annelated derivatives of imidazole, 1,2,3-triazole, pyrazine etc.
EFFECT: improved properties of the derivatives.
