Procedure

To 10 mL of a chloroform solution containing 209 mg of 7-fluoro-1-(2-(4-(3-phenyl-2-propyn-1-ylamino)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 197 mg of 7-fluoro-1-(2-(4-(3-phenyl-2-propyn-1-ylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one hydrochloride as a pale brown solid.
