실험 절차
A solution of crude (R)-tert-butyl 3-((R)-(2-(tert-butyldimethylsilyloxy)ethoxy)(3-chlorophenyl)methyl)piperidine-1-carboxylate in CH3CN (100 mL) and 2 N aq HCl (100 mL) was vigorously stirred at rt for 2 d. The solvents were removed in vacuo to give the HCl salt of 2-((R)-(3-chlorophenyl)((R)-piperidin-3-yl)methoxy)ethanol, which was used in the next step without further purification. LC-MS (3 min) tR=1.05 min m/z 272, 270 (M+H)+.
