Reaction Steps

To a solution of 4′-({2-ethyl-1-[4-(2-hydroxy-2-methylpropoxy)phenyl]-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl}methyl)biphenyl-2-carbonitrile (0.33 g) in N,N-dimethylformamide (5 mL) was added sodium hydride (0.05 g, 60%), and the mixture was stirred for 15 min. Then methyl iodide (0.08 mL) was added, and the mixture was further stirred for 2 hr. Small pieces of ice were added to the reaction mixture, and the mixture was stirred for 15 min. The reaction mixture was diluted with ethyl acetate, washed with 1 M hydrochloric acid, saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.10 g, 29%).
