実験手順

To 10 mL of a chloroform solution containing 281 mg of 1-(2-(4-((2,3-dihydro-1,4-dioxino[2,3-c]pyridin-7-yl)methylamino)piperidin-1-yl)ethyl)-7-fluoroquinoxalin-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 311 mg of 1-(2-(4-((2,3-dihydro-1,4-dioxino[2,3-c]pyridin-7-yl)methylamino)piperidin-1-yl)ethyl)-7-fluoroquinoxalin-2(1H)-one hydrochloride as a pale brown solid.
