Reaction Steps

Add triphenylphosphine (7.869 g, 30 mmol) to a solution of sec-phenylethyl alcohol (1.467 g, 12 mmol), 4-cyanophenol (1.191 g, 10 mmol) and diethyl azodicarboxylate (4.528 g, 26 mmol) in anhydrous THF (50 mL) at 0° C. Stir the reaction at ambient temperature for 12 h. Dilute with EtOAc, wash with brine, dry over Na2SO4, filter and concentrate. Purify by chromatography on silica gel eluting with EtOAc/hexane (1:8) to give (±)-4-(1-phenylethoxy)-benzonitrile with a small amount of triphenylphosphine (2.49 g total).
