Procedure
To 60 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-acetamino-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 3 mL of 1,4-dioxane and 1 mL of 4 mol/L hydrogen chloride/1,4-dioxane were added, and stirred at room temperature overnight. The solvent was removed under reduced pressure and the resulting solid was recrystallized in methanol-ethyl acetate to give 18 mg of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-5-acetaminoquinolin-2(1H)-one hydrochloride as a pale yellow solid.
