反应详情

0.25 g of ethyl 2-ethoxy-3-(4-methoxy-3-({[4-(trifluoromethyl)benzyl]amino}carbonyl)phenyl)propanoate was dissolved in 7 ml ethanol, and 3 ml of 1 N sodium hydroxide was added, and the mixture was stirred at room temperature for 14 hours. The reaction mixture was ice-cooled, neutralized with 1N hydrochloric acid, and then extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and the solvent was evaporated, to give 0.18 g of 2-ethoxy-3-(4-methoxy-3-({[4-(trifluoromethyl)benzyl]amino}carbonyl)phenyl)propanoic acid.
