Reaction Steps

To a solution (10 ml) of ethyl 4-[(2-hydroxyethyl) (methyl)amino]benzoate (500 mg, 2.24 mmol) in methanol was added 1M aqueous sodium hydroxide solution (10 ml), and the mixture was stirred at room temperature for 3 hrs. Water was added to the reaction mixture, and the mixture was washed with diethyl ether. 1M Hydrochloric acid (10 ml) was added, and the mixture was extracted with dichloromethane and concentrated under reduced pressure to give the title compound (119 mg, 27%) as a white solid.
