8-Chloro-3-cyano-2-methylthio-4-oxo-4[H]-pyrimido-[2,1-b] [1,3] benzothiazole has been prepared by the reaction of 6-Chloro-2-amino benzothiazole with ethyl-2-cyano-3,3-bismethylthioacrylate in the presence of diemethyl formamide and anhydrous potassium carbonate. Suspectibility of compound towards condensation with different reagents like aryl amines, heteryl amines, phenols and compound containing active methylene group has been investigated.
