(R)-tert-Butyl 3-((R)-(3-chlorophenyl)(2-(methoxycarbonylamino)ethoxy)methyl)piperidine-1-carboxylate (4.86 g, 11.4 mmol) was dissolved in a solution of 20% (V/V) TFA/CH2Cl2 (10 mL). The reaction mixture was stirred at rt for 1 hr. The solvent was removed in vacuo to afford methyl 2-((R)-(3-chlorophenyl)((R)-piperidin-3-yl)methoxy)ethylcarbamate as TFA salt (4.8 g, 100%), which was used for the next step directly without purification.
