(R)-tert-butyl 3-((R)-(3-chlorophenyl)(3-(methylamino)-3-oxopropoxy)methyl)piperidine-1-carboxylate (0.80 g, 1.95 mmol) was dissolved in a 20% solution of TFA in CH2Cl2 (20.6 mL) and stirred for about 1 h at rt until the reaction was complete. The solvent was removed by evaporation and the crude product was purified with preparative HPLC to afford 3-((R)-(3-chlorophenyl)((R)-piperidin-3-yl)methoxy)-N-methylpropanamide (542 mg, 1.75 mmol, 90% yield). MS (E/Z): 311 (M+H+).
