Procedimiento

101 mg of 1-(2-(4-((7-bromo-2,3-dihydro-1,4-benzodioxin-6-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one was dissolved in 3 mL of chloroform, 0.5 mL of 4 mol/L hydrogen chloride/ethyl acetate and 3 mL of chloroform were 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 92 mg of 1-(2-(4-((7-bromo-2,3-dihydro-1,4-benzodioxin-6-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one hydrochloride as a dark brown powder.
