Procedure

3-Butyryl-4-chloro-8-methylquinoline (2.48 g, 10 mmol), 2-ethylaniline (1.85 ml, 15 mmol) and 1,4-dioxan (10 ml) were stirred at room temperature overnight then heated at reflux for 30 minutes. The solvent was evaporated, the residue converted to free base and recrystallised from aqueous ethanol to give 3-butyryl-4-(2-ethylphenylamino)-8-methylquinoline (2.38 g), m.p. 117°-119°.
