실험 절차

3-Amino-1-benzylpyrrolidine [8.3 g, prepared by a method of G. C. Helsley et al., J. Med. Chem., 11, 1034 (1968)] was dissolved in methylene chloride (40 ml) and thereto acetic anhydride (5.3 g) was added dropwise with stirring under cooling with ice-water and the mixture was stirred for 1.5 hours. After addition of 2N sodium hydroxide (40 ml), the mixture was extracted with methylene chloride. The extract was washed with water and dried over anhydrous magnesium sulfate, followed by distilling off the solvent under reduced pressure to give 3-acetylamino-1benzylpyrrolidine (9.0 g) as oil.
