Versuchsvorschrift

To a solution of 15.9 g (0.1 mol) of 1-benzyl-3-pyrroline, 56.7 g (0.24 mol) of 2-mesitylenesulfonic acid dihydrate (produced by Aldrich Chemical Co., Inc.), 15.0 g of water, and 60.0 g of acetone in a round flask reactor, 31.1 g (0.13 mol) of 70% m-CPBA (m-chloroperbenzoic acid produced by Tokyo Chemical Industry Co., Ltd.) was added with stirring and allowed to react for 10 hours at room temperature without irradiation by lamps. After completion, acetone was evaporated under reduced pressure, neutralized by NaOH (aq), and extracted with toluene and water. After the solvent was evaporated under reduced pressure, 16.6 g of 1-benzyl-3,4-epoxypyrrolidine (yield 94.7%) was obtained.
