実験手順

To a solution of 4-(2-benzyloxybenzyl)benzyl chloride (0.66 g) in N,N-dimethylformamide (20 mL) was added potassium cyanide (0.40 g), and the mixture was stirred at 60° C. for 18 hours. The reaction mixture was cooled to ambient temperature, and water was added thereto. The resulting mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium hydrogen carbonate solution and brine, and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=5/1–3/1) to give [4-(2-benzyloxybenzyl)phenyl]acetonitrile (0.54 g).
