Procedure

To 1 mL of an ethanol solution containing 60 mg of methyl 2-((2-(1-(2-(7-methoxy-4-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-ylamino)ethyl)thio)benzoate, 0.1 mL of 20% aqueous sodium hydroxide solution was added at room temperature and stirred for 1 hour and 40 min. After the solvent was removed from the reaction mixture under reduced pressure, water was added, adjusted to pH 6.2 with 6.0 mol/L hydrochloric acid. The resulting solid was filtered, washed with water and diethylether to give 28 mg of 2-((2-(1-(2-(7-methoxy-4-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-ylamino)ethyl)thio)benzoic acid as a white solid.
