실험 절차
Diketene (1.64 mL, 21.3 mmol, 1.50 equiv) was added at 0° C. to a stirred solution of 1-(3-aminopropyl)-4-phenylpiperidine (3.10 g, 14.2 mmol, 1.00 equiv) in anhydrous THF (30 mL) under argon, and stirring was continued at room temperature for 1 hour. The mixture was concentrated to give 4.50 g (100%) of viscous orange oil, which was characterized spectroscopically and used for the next reaction without purification.
