Procedure
3-Butyryl-4-chloro-8-methoxyquinoline (2 g, 8 mmol), 4-aminophenol (1.24 g, 11 mmol) and 1,4-dioxan (50 ml) were heated at reflux for 2 hours, then the solid filtered off and converted to free base. Recrystallisation from ethanol and then methanol gave 3-butyryl-4-(4-hydroxyphenylamino)-8-methoxyquinoline (1.6 g), m.p. 270°-272°.
