To 5 mL of a 1,4-dioxane solution containing 206 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(6-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 5 mL of 4 mol/L hydrogen chloride/1,4-dioxane was added, and stirred at room temperature for 4 hours. The solvent was removed under reduced pressure, 1,4-dioxane was added to the residue thus obtained, and the resulting solid was filtered to give 110 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-6-methylquinolin-2(1H)-one hydrochloride as a white solid.
