実験手順

To a suspension of 4,4-diphenylpiperidine hydrochloride (195 mg, 0.712 mmol, 1.0 equiv) in EtOH (1.5 mL) was added Et3N (0.25 mL, 1.8 mmol, 2.6 equiv) followed by acrylonitrile (0.13 mL, 2.01 mmol, 2.8 equiv). The resulting solution was stirred at room temperature under argon for 15 minutes and then concentrated. Water was added, and the mixture was extracted three times with EtOAc. The combined organic extracts were dried over MgSO4 and concentrated to give 170 mg (87%) of tan solid, which was characterized spectroscopically and used for the next reaction without purification.
