Reaction Steps

To 0.30 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(3-bromo-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 6 mL of 1,4-dioxane and 2 mL of 4.0 mol/L hydrogen chloride/1,4-dioxane were added, and stirred at room temperature overnight. The resulting solid was filtered to give 0.21 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-3-bromoquinolin-2(1H)-one hydrochloride as a white solid.
