Reaction Steps
Triethylamine (1.3 mL, 9.30 mmols) and acetyl chloride (0.6 mL, 8.46) were added to THF (20 mL) solution of (3S)-1-benzyl-3-hydroxypyrrolidine (1.5 g, 8.46 mmols) by the order stated, under cooling with ice, and stirred at the same temperature for an hour. Ethyl acetate was added to the reaction liquid which then was washed with water and saturated brine, and dried over anhydrous sodium sulfate. Concentrating the reaction liquid under reduced pressure, the residue was purified on silica gel column chromatography (KP—NH, ethyl acetate:hexane=1:20) to provide the title compound (1.68 g, 90%).
