Reaction Steps

To 1 mL of methanol solution containing 0.16 g of tert-butyl (1-(2-(7-(difluoromethoxy)-4-methyl-2-oxo-1,2-dihydroquinolin-1-yl)ethyl)piperidin-4-yl)(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)carbamate, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added at room temperature, and stirred for 1 hour. Ethyl acetate was added, and the resulting solid was filtered to give 87 mg of 7-(difluoromethoxy)-1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-4-methylquinolin-2(1H)-one hydrochloride as a white solid.
