ملخص المقالة :
4-Amino-5-bromo-2-substituted-aminopyrimidines were successfully reacted with various isothiocyanates in the alkaline alumina under Microwave irradiation to achieve a group of reported 2- aminothiazolo[4,5-d]pyrimidine derivatives . These compounds also carried out a multicomponent condensation with carbondisulfid and alkylhalides to furnish a group of reported 2- alkylsulfanylthiazolo[4,5-d]pyrimidine derivatives.
