Procedure

Three grams (3.00 g) of crude N-[2-(3,4-dimethoxyphenyl)ethyl]-3-dimethylamino-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acrylamide (7.35 mmol), 30 ml of 5% hydrochloric acid and 30 ml of tetrahydrofuran were mixed and stirred at room temperature for 1.5 hours. Water was added to the reaction mixture, which was followed by extracted with ethyl acetate twice, washed with saturated brine twice, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was washed with hexane and dried to give 2.20 g of N-[2-(3,4-dimethoxyphenyl)ethyl]-3-hydroxy-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acrylamide.
