Reaction Steps

To a mixture of sodium hydride (2.86 g) and tetrahydrofuran (250 mL) were added a solution of diethyl malonate (16.7 mL) in tetrahydrofuran (100 mL) and then 4′-(bromomethyl)biphenyl-2-carbonitrile (15 g), and the mixture was stirred at room temperature for 16 hr. The reaction mixture was concentrated under reduced pressure, and the obtained residue was extracted with 5% aqueous potassium hydrogen sulfate solution and ethyl acetate. The ethyl acetate layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound as a colorless oil (18.3 g, 95%).
