Procedure
Add lithium hydroxide (0.03 g, 1.3 mmol) to the crude 3-[(R)-2-(4-cyano-phenylcarbamoyl)-pyrrolidin-1-yl]-benzoic acid ethyl ester (0.05 g, 0.14 mmol) in a 1:1:1 mixture of water:MeOH/tetrahydrofuran (3 mL). Stir the mixture at room temperature for 15 h then wash with EtOAc. Adjust the pH of the aqueous phase to slightly acidic by the addition of a 2 N solution of hydrochloric acid. Extract the mixture with methylene chloride, dry the combined organic phase over anhydrous sodium sulfate and concentrate under a stream of nitrogen to provide 0.020 g of 3-[(R)-2-(4-cyano-phenylcarbamoyl)-pyrrolidin-1-yl]-benzoic acid as a yellow oil.
