実験手順
4 M hydrogen chloride/EtOAc solution (5.0 ml) was dropwise added to an EtOAc (15 ml) solution of tert-butyl 4-[3-(4-isoquinolin-1-ylpiperazin-1-yl)propyl]piperidine-1-carboxylate (1.44 g), followed by stirring overnight. The solvent was evaporated, the solid was washed with EtOAc and collected by filtration to obtain 1-[4-(3-piperidin-4-ylpropyl)piperazin-1-yl]isoquinoline dihydrochloride (1.32 g) as a white solid.
