A solution of 1-methyl-4-phenylpiperidine-4-carbonitrile (1.0 g, 4.99 mmol) in THF (25 mL) was slowly added to a suspension of LAH (0.379, 9.99 mmol) in THF (10 mL). The reaction was stirred for 2 hours and then quenched with sodium sulfate decahydrate. This was stirred for 30 minutes, and then ethyl acetate was added. The mixture was stirred 10 minutes, and then filtered on celite. The filtrate was concentrated on rotovap to give the desired compound (0.916 g, 96%) as an oil. 1H NMR (400 MHz, CDCl3) δ ppm: 1.79-1.89 24H, m), 2.18-2.28 (7H, m), 2.55-2.65 (2H, m), 2.77 (2H, s), 7.21-7.27 (1H, m), 7.28-7.39 (4H, m).
