Abstract

Alkyl 2-[2-cyano-2-(2-pyridinyl)ethenyl]amino-3-dimethylaminopro-penoates (8) and (9) were transformed by heating into alkyl 2-[2-cyano-2- (2-pyridinyl)ethenyl]amino-3-[2-methoxycabonyl-4-(2-pyridinyl)-1H-pyrrol-3-yl]aminopropenoates (12) and (13). Compounds (8) and (9) can be transformed in the presence of primary aliphatic amines into substituted pyrrolo[3,2-d]pyrimidines (17-19).
