Reaction Steps
To a solution of (R)-tert-butyl 3-((2-azidoethoxy)(3-chloro-2-fluorophenyl)methyl)-piperidine-1-carboxylate (2.6 g, 6.31 mmol) in EtOAc (50 mL) was added wetted Pd/C (0.1 g) and the mixture was stirred overnight under a hydrogen atmosphere maintained by a balloon. The reaction mixture was filtered through a pad of Celite and the solvent was removed to give (R)-tert-butyl 3-((2-aminoethoxy)(3-chloro-2-fluorophenyl)methyl)piperidine-1-carboxylate which was submitted to reverse phase the preparative HPLC to give (R)-tert-butyl 3-((S)-(2-aminoethoxy)(3-chloro-2-fluorophenyl)methyl)piperidine-1-carboxylate (990 mg, 81%) and (R)-tert-butyl 3-((R)-(2-aminoethoxy)(3-chloro-2-fluorophenyl)methyl)piperidine-1-carboxylate (792 mg, 65%). MS (E/Z): 387 (M+H+).
