To 1.5 mL of methanol solution containing 0.182 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-methoxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1.5 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added, and stirred for 1.5 hours. Ethyl acetate was added, and the resulting solid was filtered to give 0.13 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-5-methoxyquinolin-2(1H)-one hydrochloride as a pale yellow solid.
