実験手順

To a solution of 4′-[(6-ethyl-2,4-dioxo-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl)methyl]biphenyl-2-carbonitrile (1.50 g), 2-bromo-1-(4-fluorophenyl)ethanone (1.01 g) in DMF (50 ml) was added under ice-cooling 60% sodium hydride (0.093 g) and the mixture was stirred at 70° C. for 1 hr. The solvent was concentrated, water was added, and the mixture was extracted with ethyl acetate and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. Silica gel column chromatography gave the title compound as a colorless solid (1.40 g).
