Reaction Conditions

Reaction Steps

A mixture of commercially available 4-phenylpiperidine (10 g, 62 mmol), pyridine (5.7 mL, 70.5 mmol), and tetrahydrofuran (80 mL) was stirred at 0° C. and a mixture of acetyl chloride (5 mL, 70.3 mmol) and tetrahydrofuran (20 mL) was dripped over 10 minutes. The mixture was stirred under nitrogen atmosphere at 25° C. for 14 hours. Ethyl acetate (100 mL) and water (100 mL) were added to the reaction liquid for separation. The aqueous layer was extracted with ethyl acetate (100 mL), then the organic layers were combined, and the resultant was washed with a saturated aqueous sodium bicarbonate solution (100 mL), water (100 mL), and then a saturated saline solution (50 mL). The organic layer was dried over anhydrous magnesium sulfate and then the solvent was evaporated to obtain the title compound (12.3 g, 98%).
