Procedure

To a solution of 4′-{[1-(4-acetylphenyl)-2-ethyl-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl]methyl}biphenyl-2-carbonitrile (0.78 g) in tetrahydrofuran (20 mL) was added methyllithium (2.4 mL, 1.4 M diethyl ether solution) under ice-cooling, and the mixture was stirred for 1 hr. A saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate, washed with 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 (0.30 g, 37%).
