実験手順

17.7 g (60.9 mmol) of 4-benzyloxy-2-chloro-benzoic acid ethyl ester and 4.87 g (122 mmol) of sodium hydroxide were added to a mixed solvent consisting of 180 mL of methanol and 18 mL of water followed by refluxing for 6 hours. After cooling, concentrated hydrochloric acid was added to bring to a pH of 5 followed by filtering out the precipitate. The precipitate was washed with water and dried to obtain 8.5 g of a white solid.
