Reaction Steps

To 5 mL of an ethyl acetate solution containing 0.76 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-chloro-7-fluoro-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 5 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and stirred at room temperature. The resulting solid was filtered to give 572 mg of (1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-chloro-7-fluoroquinolin-2(1H)-one hydrochloride as a brown solid.
