To a mixture of 3-[(tert-butoxycarbonyl)(2-methoxyethyl)amino]benzoic acid (0.57 g) and ethyl acetate (10 ml) was added a 4 M hydrogen chloride/ethyl acetate solution (5.0 ml) under ice-cooling, followed by stirring at room temperature over one night. The solid precipitated was collected by filtration to obtain 3-[(2-methoxyethyl)amino]benzoic acid hydrochloride (0.38 g).
