실험 절차

3-Butyryl-4-chloro-8-methoxyquinoline (20.2 g, 0.077 mol) and o-anisidine (15 ml, 0.11 mol) were heated under reflux in 1,4-dioxan (150 ml) for 1 hour. The solvent was evaporated and the residue dissolved in dichloromethane and washed with dilute hydrochloric acid, sodium bicarbonate solution and brine. The solution was dried, filtered and evaporated to a yellow solid, which was triturated with ether to give 3-butyryl-4-(2-methoxyphenylamino)-8-methoxyquinoline (18.55 g, 68.75%) m.p. 159°-161°.
