Abstract

Diethyl 4-(6-chloroimidazo[2,1-b]thiazol-5-yl)-2,6-dimethyl-1,4-dihydropyridine- 3,5-dicarboxylate and ethyl 4-(6-chloroimidazo[2,1-b]thiazol-5-yl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate were obtained simultaneously by the Biginelli reaction using a green protocol and curtailing reaction time.
