3-(2,2′-Bisethylcarbamoyl-2-phenylethoxy)propionic acid methyl ester (125 mg) was dissolved in THF (0.5 mL) and MeOH (0.5 mL), and 1N sodium hydroxide (0.5 mL) was added thereto. The solution was stirred at room temperature for 1 hour and then concentrated. The residue was acidified with 1N hydrochloric acid and extracted with ethyl acetate. The extract was washed with water and concentrated to give 3-(2,2′-bisethylcarbamoyl-2-phenylethoxy)propionic acid (115 mg).
