70 °C

0.59 g of ethyl 2-[4-methoxy-3-({[4-(trifluoromethyl)benzoyl]amino}methyl)benzyl]butanoate was dissolved in 5 ml ethanol, and 2 ml of 1 N sodium hydroxide was added, and the mixture was stirred at 70° C. for 4 hours. The reaction mixture was ice-cooled and neutralized with 1N hydrochloric acid, followed by extracting with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and the solvent was evaporated, to give 0.50 g of 2-[4-methoxy-3-({[4-(trifluoromethyl)benzoyl]amino}methyl]benzyl]butanoic acid.
