Chloroform → 7-methoxy-1-(2-(4-((naphthalen-2-yl)methylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one hydrochloride

Participants

Reaction Steps

To a mixed solution of 10 mL chloroform and 10 mL ethyl acetate containing 0.41 g of 7-methoxy-1-(2-(4-((naphthalen-2-yl)methylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one, 3 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 452 mg of 7-methoxy-1-(2-(4-((naphthalen-2-yl)methylamino)piperidin-1-yl)ethyl)quinoxalin-2(1H)-one hydrochloride as a pale brown solid.
