(RS)-1-Benzyl-2-bromomethylpiperidine, D31 (4.2 g) was dissolved in dry dimethylsulphoxide (15 ml) and treated with sodium cyanide (5.0 g). The solution was then stirred at 85° C. under argon for 18 h. The reaction solution was then poured into water (300 ml) and extracted with dichloromethane (2×200 ml). The organic solution was dried (MgSO4) and the solvent removed in vacuo. Chromatography (silica gel, diethyl ether/petroleum ether mixtures) afforded the title compound (3.3 g).
