Vorschrift

To 5 mL of an ethyl acetate solution containing 540 mg of 1-(2-(4-((2,3-dihydro-1,4-dioxino[2,3-c]pyridin-7-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxy-quinoxalin-2(1H)-one, 2 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature. The resulting solid was filtered to give 661 mg of 1-(2-(4-((2,3-dihydro-1,4-dioxino[2,3-c]pyridin-7-yl)methylamino)piperidin-1-yl)ethyl)-7-methoxy-quinoxalin-2(1H)-one hydrochloride as a pale green solid.
