Procedure

1-Benzyloxycarbonyl-3-mesyloxymethylpiperidine (WO 0100207; 8.4 g) was dissolved in DMSO (100 ml) and sodium cyanide (1.6 g) was added. The mixture was heated to 100° C. and stirred continuously under an argon atmosphere for 6 hours. The mixture was cooled and poured into water (200 ml). The product was extracted with EtOAc, washed with ferrous sulphate solution (10% w/w), dried and evaporated in vacuo. TLC (40% EtOAc/petroleum ether (60/80) Rf. 0.54.
