实验过程

First, 2.49 g (9.6 mmol) of (S)-1,4-bis(methanesulfonyloxy)pentane produced in Example 5 and 5.13 g (47.9 mmol) of benzylamine were stirred at 70° C. for three hours. Subsequently, 30 mL of ethyl acetate and 4.0 g of a 20 weight percent aqueous solution of sodium hydroxide were added to the mixture to perform an extraction. The organic layer was concentrated under a reduced pressure to obtain a yellow oily substance. This product was purified by silica gel column chromatography. Thus, (R)-1-benzyl-2-methylpyrrolidine was obtained as a light yellow oily substance (1.83 g, yield: 100%).
