Procedure
To a solution of 185 mg of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-b)pyridin-7-ylmethyl)amino)piperidin-1-yl)ethyl)-7-fluoro-1,5-naphthyridin-2(1H)-one in 4 mL of ethyl acetate, 2 mL of 4 mol/L hydrogen chloride/ethyl acetate was added, and the mixture was stirred at room temperature for 1 hour. The solid was filtered off to obtain 244 mg of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-b)pyridin-7-ylmethyl)amino)piperidin-1-yl)ethyl)-7-fluoro-1,5-naphthyridin-2(1H)-one hydrochloride as a white solid.
