Abstract

The synthesis of highly substituted 7-methyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylate derivatives by one-pot reaction of aminothiazole, aldehyde and ethyl acetoacetate under microwave irradiation have been accomplished without any catalyst. This approach provides a simple, rapid, and green method for the synthesis of 7-methyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylate derivatives.
