3-Butyryl-4-chloro-8-methylquinoline (1.24 g, 5 mmol) and 4-chloro-2-methylaniline (1.06 g, 7.5 mmol) in dioxan (5 ml) were heated at reflux for 30 minutes, then allowed to cool. The product was filtered off, converted to free base, and recrystllised from methanol, to give 3-butyryl-4-(4-chloro-2-methylphenylamino)-8-methylquinoline (0.73 g), m.p. 166°-167°.
