To 10 mL of an ethyl acetate solution containing 1-(2-(4-(4-ethylbenzylamino)piperidin-1-yl)ethyl)-7-fluoroquinoxalin-2(1H)-one, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature for 10 min. The resulting solid was filtered to give 292 mg of 1-(2-(4-(4-ethylbenzylamino)piperidin-1-yl)ethyl)-7-fluoroquinoxalin-2(1H)-one hydrochloride as a pale brown solid.
