Procedure
3-Butyryl-4-chloro-8-methoxyquinoline (3.95 g, 15 mmol), 4-amino-3-methylphenol (2.46 g, 20 mmol) and 1,4-dioxan (15 ml) were warmed briefly to reflux, then the solid filtered off and washed with ethyl acetate. Conversion to free base and recrystallisation from ethanol gave 3-butyryl-4-(4-hydroxy-2-methylphenylamino)-8-methoxyquinoline (1.79 g, 34%), m.p. 252°-253°.
