Procedure
Add 10% aqueous solution of sodium hydroxide (2.5 mL, 6.2 mmol) to a suspension of 3-[(R)-1-(4-cyano-phenylcarbamoyl)-ethoxy]-benzoic acid methyl ester (0.59 g, 0.81 mmol) in a 1:1 mixture of water: MeOH (20 mL). Heat the mixture at 50° C. for 1 h then cool to room temperature and adjust the pH of the mixture to approximately pH 5 by the addition of a 2 N solution of hydrochloric acid. Extract the mixture with EtOAc and wash the combined organic phase with brine, dry over anhydrous sodium sulfate and concentrate under reduced pressure to provide 0.55 g of 3-[(R)-1-(4-cyano-phenylcarbamoyl)-ethoxy]-benzoic acid as a foam.
