반응 단계

A mixture of (R)-tert-butyl 3-((R)-1-(3-chlorophenyl)-1-(2-ethoxy-2-oxoethoxy)ethyl)piperidine-1-carboxylate (0.0580 g, 0.136 mmol), 2 NHCl (50 mL), and CH3CN (50 mL) was vigorously stirred at rt for 24 h. After the reaction mixture was evaporated under reduced pressure, the crude product ethyl 2-((R)-1-(3-chlorophenyl)-1-((R)-piperidin-3-yl)ethoxy)acetate was directly used in the next step without further purification. MS ESI +ve m/z 328 (M+H).
