To 1 mL of methanol solution containing 85 mg of tert-butyl (1-(2-(7-cyclopropoxy-4-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)carbamate, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added at room temperature, and stirred for 1.5 hours. 1 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added, and further stirred for 30 min. Ethyl acetate was added, and the resulting solid was filtered to give 60 mg of 7-cyclopropoxy-1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-methylquinolin-2(1H)-one hydrochloride as a white solid.
