Procedure

A mixture of N-(2-tert-butoxycarbonylaminoethyl)phthalimide (2.5 g) and 4N solution of hydrogen chloride in ethyl acetate (25 ml) was stirred for 1 hour at ambient temperature. The resulting precipitates were collected by filtration and washed with ethyl acetate to give N-(2-aminoethyl)phthalimide hydrochloride (1.89 g) as colorless crystals.
