To 1 mL of an ethyl acetate solution containing 30 mg of tert-butyl(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-methoxycarbonyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature for 42 hours. The resulting solid was filtered to give 18 mg of methyl 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-1,2-dihydro-2-oxoquinoline-4-carboxylate hydrochloride as a yellow solid.
