6-Amino-4-aryl-7-phenyl-3-(phenylamino)-4,7-dihydro-3Н-[1,2]dithiolo[3,4-b]pyridine-5-carbonitriles were synthesized via the reaction of arylmethylidenemalononitriles with dithiomalonic acid dianilide in the presence of an excess of morpholine. The structure of 6-amino-4-(3,4-dimethoxyphenyl)-7-phenyl-3-(phenylamino)-4,7-dihydro-3Н-[1,2]dithiolo[3,4-b]pyridine-5-carbonitrile was studied by X-ray structural analysis.
