Reaction Steps

To a stirred solution of 3-(4-benzyl-1-piperazinyl)propylamine (2.01 g/8.61 mmol) in tetrahydrofuran (15 ml) were added 2 N NaOH (6.5 ml/13.0 mmol) and 2-chloroethylchloroformate (1.38 ml/12.9 mmol), and the mixture was stirred for 1 d. Water (50 ml) was added to the mixture and the whole was extracted with ethyl acetate (50 ml). The extract was washed with brine (50 ml), dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (NH2 gel/dichloromethane) to give a colorless oil.
