Reaction Steps
To a solution of 3,6-dimethyl-7-hydroxy-5H-thiazolo[3,2-a]pyrimidin-5-one (526 mg) and potassium carbonate (574 mg) in DMF (10 ml) was added 4-(6-chloronicotinoyl)benzyl bromide (852 mg) and the mixture was stirred at 80° C. for 2 hours. This reaction mixture was concentrated and the residue was diluted with water-ethyl acetate and extracted with ethyl acetate. The extract was purified by silica gel column chromatography (hexane: ethyl acetate =2:1) and recrystallized from ethyl acetate to provide the title compound as colorless solid (300 mg).
