To 0.5 mL of methanol solution containing 58 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-methyl-7-((methylamino) carbonyl)-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 0.5 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added, and stirred for 5.5 hours. Ethyl acetate was added, and the resulting solid was filtered to give 0.032 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-N-methyl-4-methyl-2-oxo-1,2-dihydroquinoline-7-carboxamide hydrochloride as a white solid.
