To a solution of the enantiomeric mixture of cis-4-benzylamino-1-tert-butoxycarbonyl-3-fluoropiperidine (prepared according to the procedures of J. Med. Chem. 1999, 42, 2087-2104, 1.0 g, 3.2 mmole) in EtOH (40 mL) was added 3 N HCl (2.5 L) and 10% Pd/C (50 mg). The reaction was shaken under H2 (40 psi) on a Parr apparatus for 14 h, then was filtered through Celite®. The filtrate was concentrated under reduced pressure, and the residue was purified by flash chromatography on silica gel (10% MeOH/CHCl3) to afford the title compound (370 mg, 53%) as a white solid.
