2.00 g of (R)-1-benzyl-3-(p-toluenesulfonyloxy)pyrrolidine (J. Med. Chem., 1992, 35, 4205-4208) was dissolved in 12 ml of ethanol, 1.63 g of pyrrolidine was added, and then the mixture was stirred at 140° C. for 20 hours in a sealed tube. The reaction solution was concentrated under reduced pressure, mixed with water, followed by extraction with ethyl acetate, and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography to obtain 0.97 g of the objective compound as a brown oily product.
