Procedure
2-Fluoro-4-aminophenol (0.8 g, 6 mmol) and 3-butyryl-4-chloro-8-methoxyquinoline (1.5 g, 5.7 mmol) were heated together under reflux in 1,4-dioxan (50 ml) for 1 hour. The solvent was evaporated and the residue was dissolved in dichloromethane, washed with water, sodium hydrogen oarbonate solution and brine then dried and evaporated. The residue was recrystallised from methanol-water to afford 3-butyryl-4-(3-fluoro-4-hydroxyphenylamino)-8-methoxyquinoline, m.p. 266°-268°.
