A mixture of methyl 2-(6-ethyl-2,4-dioxo-1,4-dihydrothieno[2,3-d]pyrimidin-3(2H)-yl)propanoate (9.9 g), 4′-(bromomethyl)biphenyl-2-carbonitrile (11.5 g), potassium carbonate (9.7 g) and acetonitrile (500 mL) was stirred at 50° C. for 2 hr. Insoluble material was filtered off, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound as a colorless amorphous solid (15 g, 90%).
