Reaction Steps

To a suspension of 0.34 g (0.85 mmol) of {1-[2-(3-chloro-benzoylamino)-phenyl]-piperidin-4-yl}-acetic acid ethyl ester in a 1:1 mixture of water:methanol (10 mL) is added 0.64 mL (1.6 mmol) of sodium hydroxide as a 10% aqueous solution. The mixture is heated to 60° C. for 3 hours then cooled to room temperature, diluted with water, and the pH of the mixture is adjusted to approximately pH 5 by the addition of a 2 N solution of hydrochloric acid. The mixture is extracted with ethyl acetate and the combined organic phase is dried over anhydrous sodium sulfate and concentrated under reduced pressure to provide 0.29 g (92%) of {1-[2-(3-chloro-benzoylamino)-phenyl]-piperidin-4-yl}-acetic acid as a yellow oil.
