To 55 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(5-(3-ethylureido)-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 for 3 hours. The resulting solid was filtered to give 26 mg of 1-ethyl-3-(1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)quinolin-2(1H)-on-5-yl)urea hydrochloride as a yellow solid.
