Procedimiento

To 1.5 mL of methanol solution containing 0.17 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-fluoro-4-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 1.5 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added, and stirred for 4 hours. Ethyl acetate was added, and the resulting solid was filtered to give 0.15 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-fluoro-4-methylquinolin-2(1H)-one hydrochloride as a white solid.
