FIELD: organic chemistry.
SUBSTANCE: invention relates to a method for producing amides 6-amino-7-phenyl-3-(phenylimino)-4,7-dihydro-3H-[1,2]dithiolo[3,4-b]pyridine- 5-carboxylic acid of general formula 1, where Ar = unsubstituted or substituted aromatic or heterocyclic substituent. The method includes the interaction of equimolar amounts of ArCHO, where Ar is an unsubstituted or substituted aromatic or heterocyclic substituent, with cyanoacetamide in the presence of catalytic amounts of morpholine in ethanol at a temperature of 40-50°C; adding to the resulting product an equimolar amount of dithiomalondianilide and an excess of morpholine at a temperature of 50-60°C within 3-5 hours.
EFFECT: creation of a method for producing amides of 6-amino-7-phenyl-3-(phenylimino)-4,7-dihydro-3H-[1,2]dithiolo[3,4-b]pyridine-5-carboxylic acid.
