実験手順

To 1 mL of an ethyl acetate solution containing 104 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4,7-dichloro-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 2 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature. The resulting solid was filtered to give 62 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4,7-dichloroquinolin-2(1H)-one hydrochloride as a pale yellow solid.
