Participants

Reaction Steps

To a mixture of 4′-[(2,4-dioxo-6-propoxy-3,4-dihydropyrimidin-1(2H)-yl)methyl]-biphenyl-2-carbonitrile (1 g), 1-bromo-3,3-dimethylbutan-2-one (0.59 g) and N,N-dimethylformamide (15 mL) was added 60% sodium hydride (0.17 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 obtained residue was purified by silica gel column chromatography to give the title compound as a colorless amorphous solid (0.8 g, 26%).
