실험 절차

To a mixture of 4′-[(6-ethyl-2,4-dioxo-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl)methyl]biphenyl-2-carbonitrile (5 g), 2-bromo-1-(3-bromo-4-methoxyphenyl)ethanone (4.4 g) and N,N-dimethylformamide (300 mL) was added 60% sodium hydride (0.57 g), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate, washed with 5% potassium hydrogensulfate and then saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The precipitated solid was collected by filtration to give the title compound as colorless crystals (3.4 g, 43%).
