Procedure

To a solution (10 ml) of ethyl 4-[(2-methoxyethyl)(methyl)amino]benzoate (467 mg, 1.97 mmol) in methanol was added 1M aqueous sodium hydroxide solution (10 ml), and the mixture was stirred at 50° C. for 3 hrs. The reaction mixture was concentrated under reduced pressure, and water and diethyl ether were added to the residue. The organic layer was separated. The aqueous layer was neutralized with 1M hydrochloric acid (10 ml) and extracted with ethyl acetate. The extract was dried over anhydrous MgSO4 and concentrated under reduced pressure to give the title compound (340 mg, 82%) as a white solid.
