An efficient one-pot method to synthesize thiazolo[3,2-a]pyrimidine derivatives has been developed. The method involves the temperature controlled functionalization-annulation of 5-ethoxycarbonyl-6-methyl-4-aryl-3,4-dihydro-2(1H)-pyrimidin-2-thione (DHPM) derivatives with in-situ generated bromo-ketones received by reaction of different α-H carbonyl compounds with bromine.
