To 0.60 grams of sodium hydroxide dissolved in 10 ml of ethanol was added 3.30 g of the above ester. The mixture was stirred at room temperature for 4 hours, after which water was added, and the mixture was washed with toluene. The organic phase was discarded. The product was acidified, extracted into ether, washed with water, dried and solvent removed to yield 2-(2-chloro-4-trifluoromethylphenylamino)-3-methylbutanoic acid, m.p. 132°-135°, in 90% yield.
