実験手順

To 2 mL of an ethyl acetate solution containing 31 mg of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)amino)-3-fluoropiperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one, 0.20 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added at room temperature, and the solvent was removed under reduced pressure, diethyl ether was added and the resulting solid was filtered to give 25 mg of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)amino)-3-fluoropiperidin-1-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one hydrochloride as a pale brown solid.
