Reaction Steps
To a solution of 15.9 g (0.1 mol) of 1-benzyl-3-pyrroline, 12.0 g (0.12 mol) of 98% sulfuric acid, 15.0 g of water, and 60.0 g of acetone in a quartz round flask reactor, 45.6 g (0.20 mol) of (NH4)2S2O8 (ammonium peroxydisulfate produced by Mitsubishi Gas Chemical Industry Co., Ltd.) was added with stirring and allowed to react for 5 days at room temperature with irradiation by 500 W Xe lamps (UXL-500D xenon lamp produced by Ushio). After evaporation of acetone under reduced pressure, continuously 32.1 g (0.3 mol) of benzylamine (produced by Katayama Chemical Industry Co., Ltd.) was added to the reaction mixture and stirred for 5 hours at 100° C. After completion, excess benzylamine was removed by distillation under reduced pressure, and extracted with toluene and water. After the solvent was evaporated under reduced pressure, 20.9 g of 1-benzyl-4-benzylamino-3-pyrrolidinol (yield 74.0%) was obtained.
