To 5 mL of a chloroform solution containing 169 mg of 7-methoxy-1-(2-(4-((2-oxo-1,2,3,4-tetrahydroquinolin-7-ylmethyl)amino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate and 5 mL of chloroform were 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 166 mg of 7-methoxy-1-(2-(4-((2-oxo-1,2,3,4-tetrahydroquinolin-7-ylmethyl)amino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one hydrochloride as a pale brown powder.
