실험 절차
A slurry of 3.0 g (0.0152 mole) of powdered 2-phenylcyclopentylamine hydrochloride and 3 ml of 5,O-dimethylbutyrolactim is allowed to stand at room temperature for 6 days with occasional stirring during which time sufficient ethanol is added to maintain the slurry. The slurry is then cooled to -20° C., and after about four hours a precipitate forms. The precipitate is collected and recrystallized several times from acetone-methanol to give 5-methyl-2-[(2-phenylcyclopentyl)imino]pyrrolidine hydrochloride, M.P. 175°-178° C.
