To a mixed solution of 20 mL chloroform and 10 mL ethyl acetate containing 255 mg of 7-fluoro-1-(2-(4-((naphthalen-2-yl)methylamino)piperidin-1-yl)ethyl)-quinoxalin-2(1H)-one, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature for 10 min. The solvent was removed under reduced pressure, ethyl acetate was added, and the resulting solid was filtered to give 257 mg of 7-fluoro-1-(2-(4-((naphthalen-2-yl)methylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one hydrochloride as a pale brown solid.
