A mixture of 12.2 g of 5-(3,4-dichlorophenoxy)-6-methoxy-4-methyl-8-[(4-phthalimido-1methylbutyl)amino]quinoline (21.6 mM) and 4 ml of 98% hydrazene hydrate in 500 ml of ethanol was refluxed 5 hours. The reaction mixture was evaporated under vacuum and the residue was partitioned between 400 ml of 10% potassium hydroxide and 400 ml of ethyl acetate. The organic layer was washed twice with 300 ml of 10% potassium hydroxide then four times with water, dried with anhydrous sodium sulfate and evaporated. The residue was used in the next reaction with out further purification.
