Reaktionsschritte

To 2 mL of a methanol solution containing 0.14 g of 1-(2-(4-(4-ethylbenzylamino)piperidin-1-yl)ethyl)-7-methoxy-N-methyl-2-oxo-1,2-dihydroquinoline-4-carboxamide, 1 mL of 4 mol/L hydrogen chloride/ethyl acetate was added at room temperature, and the solvent was removed under reduced pressure. Ethyl acetate was added to the residue thus obtained, and the resulting solid was filtered to give 0.15 g of 1-(2-(4-(4-ethylbenzylamino)piperidin-1-yl)ethyl)-7-methoxy-N-methyl-2-oxo-1,2-dihydroquinoline-4-carboxamide hydrochloride as a pale yellow solid.
