Методика

To a solution of 0.21 g of tert-butyl (2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)(1-(2-(7-fluoro-2-oxo-1,5-naphthyridin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate in 4 mL of ethanol, 4 mL of a 6.0 mol/L hydrogen chloride/ethanol solution was added at room temperature, and the mixture was stirred for 1 hour 30 minutes. The solvent was distilled off under reduced pressure, diethyl ether was added to the resultant residue, and the solid was filtered off to obtain 0.21 g of 1-(2-(4-((2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)amino)piperidin-1-yl)ethyl)-7-fluoro-1,5-naphthyridin-2(1H)-one hydrochloride as a light yellow solid.
