Reaction Steps
4-piperidinol (2 g, 19.8 mmol) was added to dichloromethane (20 mL), and cooled to an internal temperature of 0-5° C. Then, triethylamine (3.31 mL, 23.7 mmol) was added thereto and stirred for 30 min. Pivaloyl chloride (2.62 g, 21.8 mmol) was dropwise added thereto and heated to room temperature. The reaction mixture was stirred at room temperature for 5 hours. After completion of the reaction, the reaction mixture was mixed with a saturated aqueous solution of ammonium (50 mL) and extracted twice with dichloromethane (50 mL). The organic layer thus obtained was dried over anhydrous magnesium sulfate, and filtered and distilled under reduced pressure to obtain the title compound (3.9 g).
