To a mixture of 4′-{[2,4-dioxo-6-(2,2,2-trifluoroethyl)-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl]methyl}biphenyl-2-carbonitrile (1.5 g), 2-bromo-1-(4-fluorophenyl)ethanone (0.89 g) and N,N-dimethylformamide (50 mL) was added 60% sodium hydride (0.16 g), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate, washed successively with 1N hydrochloric acid and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was recrystallized from tetrahydrofuran to give the title compound as colorless crystals (1.08 g, 55%).
