Procedure

10% Pd/C (500 mg) was added to a solution of 1-benzylpiperidin-4-yl acetate [(11 g, 47 mmol), J. Org. Chem. 68(2), 613-616; 2003] in a mixture of ethanol and water (90:10, 110 mL), and the mixture was stirred at 60° C., under 60 psi of hydrogen gas for 18 hours. The reaction mixture was then filtered through Arbocel®, washing through with ethanol, and the filtrate was concentrated in vacuo to afford the title product in 92% yield, 7.2 g.
