To a mixed solution of 10 mL chloroform and 4 mL ethyl acetate containing 0.44 g of 1-(2-(4-(3-fluoro-4-methylbenzylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one, 2 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature. The solvent was removed under reduced pressure, ethyl acetate was added, and the resulting solid was filtered to give 422 mg of 1-(2-(4-(3-fluoro-4-methylbenzylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one hydrochloride as a brown solid.
