실험 절차

Isonipecotamide (19.4 g) and triethylamine (42 mL) were dissolved in dichloromethane (500 mL), and benzyloxy chlorocarbonate (24 mL) was added thereto under ice-cooling. The mixture was stirred at room temperature for 18 hr. The reaction mixture was added to saturated aqueous sodium hydrogencarbonate solution, and the mixture was extracted with chloroform. The extract was dried and concentrated under reduced pressure to give 1-benzyloxycarbonyl-4-carbamoylpiperidine (33.3 g) as a white solid.
