Procedure

To a solution of 6-methyl-2-propylpyrimidin-4(3H)-one (8 g) and 4′-(bromomethyl)biphenyl-2-carbonitrile (15.7 g) in acetonitrile (200 mL) was added potassium carbonate (14.5 g), and the mixture was stirred at 50° C. for 12 hr. The insoluble material was filtered off, and the filtrate was concentrated. The residue was purified by silica gel column chromatography to give the title compound (8.44 g, 47%) as a colorless solid.
