Abstract
Oxothiazolopyrimidine compounds 2(a–e) were synthesized under reflux condition by a simple one-pot condensation reaction of the pyrimidine derivative 1 and chloroacetylchloride in the presence of silver acetate as a catalyst. In a similar way the thiazolopyrimidine 3 and oxothiazolopyrimidine 4 were synthesized by reaction of pyrimidine derivative 1 with 1,2-dibromoethane and 2-bromopropanoic acid respectively. The yields of products following recrystallization from ethanol were of the order of 55–89%.
