Abstract

FIELD: organic chemistry. SUBSTANCE: method involves cyclization reaction of 2,3-diamino-5-bromo-6-methylpyridine at boiling point of reaction mixture and at azeotropic water distillation off. Cyclization reaction is carried out in medium of n- or isoamylformate at molar ratio of 2,3-diamino-5-bromo-6-methylpyridine : n- (iso)-amylformate = = 1:(1.5-3). EFFECT: improved method of synthesis.
