Versuchsvorschrift

To a solution of 0.23 g of tert-butyl (1-(2-(7-methoxy-2-oxo-1,5-naphthyridin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate in 5 mL of ethanol, 5 mL of a 6.0 mol/L hydrogen chloride/ethanol solution was added at room temperature and the mixture was stirred for 1 hour. The solvent was distilled off under reduced pressure, diethyl ether was added to the resultant residue, and the solid was filtered off to obtain 0.22 g of 1-(2-(4-aminopiperidin-1-yl)ethyl)-7-methoxy-1,5-naphthyridin-2(1H)-one hydrochloride as a light yellow solid.
