실험 절차

To a stirred solution of 1-benzyl-N-methoxy-N-methylpiperidine-4-carboxamide (11.5 g, 44 mmol) in diethyl ether (150 mL) at 0° C. was added methyl magnesium bromide (15.7 g, 132 mmol), drop-wise over 10 min. The resulting mixture was stirred at 25-30° C. for 2 h. After completion of the reaction, the mixture was treated with EtOAc and saturated NH4Cl solution. The separated organic layer was washed with brine and dried over anhydrous sodium sulfate and concentrated under vacuum to afford 1-(1-benzylpiperidin-4-yl)ethanone product. [M+1]=218.1
