To a solution of 2-benzyl 3-methyl(2S,3S,5S)-1-benzyl-5-(1-ethoxyethoxy)piperidine-2,3-dicarboxylate (3.80 g, 0.00834 mol) in 67 mL of THF was added 13 mL of water followed by 13 mL of 1 N HCl. The mixture was stirred at rt for 1 h. After diluted with ethyl acetate, the mixture was neutralized with 1N NaOH, washed with brine, dried. The residue after concentration was purified on column, eluting with 0 to 50% EtOAc in hexane, to generate the corresponding alcohol compound (2.90 g, 90.6%). MS (ESI): (M+H)+=384.1.
