実験手順

To a mixture of 4′-[(6-ethyl-2,4-dioxo-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl)methyl]biphenyl-2-carbonitrile (1.0 g), 1-bromo-3,3-dimethylbutan-2-one (0.52 mL) and N,N-dimethylformamide (8 mL) was added 60% sodium hydride (0.16 g), and the mixture was stirred at room temperature for 24 hr. To the reaction mixture was added ethyl acetate and water, and the mixture was extracted with ethyl acetate. The organic layer was successively washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound as a pale-yellow amorphous solid (0.76 g, 61%).
