Versuchsvorschrift
Hydrazine hydrate (6.54 ml) was added to a ethanol solution (250 ml) of 2-[3-(1-methyl-2-oxo-1,2-dihydroquinolin-6-yloxy)propyl]isoindole-1,3-dione (16.28 g), and stirred while heating under reflux for 2 hours. The reaction mixture was concentrated under reduced pressure. A 1N-sodium hydroxide aqueous solution was added to the residue, and stirred for 30 minutes, and extraction with dichloromethane was performed. The organic layer was washed with water and a saturated sodium chloride aqueous solution, in this order. The organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound (8.04 g) as a colorless oil.
