Reaction Steps

To 30 ml of ethanol, 1.52 g of 2-[3-(4-quinolin-2-ylpiperazin-1-yl) propyl]isoindol-1,3-dione (a compound shown in Pol. J. Chem., 75, 71-78 (2001)) was added, followed by addition of 1.50 g of hydrazine monohydrate as dissolved in 10 ml of ethanol and 7 hours' heating under reflux. After cooling the reaction system, insoluble matter was removed by filtration and the solvent was distilled off under reduced pressure. After being rendered to alkaline with 5N sodium hydroxide, the residue was extracted with chloroform, washed with saturated brine, dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to provide 0.99 g (96%) of 2-[4-(3-aminopropyl)piperazin-1-yl]quinoline.
