3-Butyryl-4-(2-methylphenylamino)-8-hydroxyquinoline (3.2 g, 10 mmol) and potassium t-butoxide (5.0 g, 40 mmol) were dissolved in dry DMF (100 ml) and N-(3-chloropropyl)-N-methylbenzylamine hydrochloride (4.1 g, 16 mmol) added. The temperature was raised to 90° and the mixture stirred for 2 hours, then poured into water and extracted with ethyl acetate. Drying, evaporation of the solvent, chromatography (silica gel, 0-3% methanolic ammonia in chloroform) and crystallisation from ether gave 3-butyryl-4-(2-methylphenylamino)-8-(3-(N-benzyl-N-methylamino)propoxy)quinoline (0.7 g, 15%), m.p. 100°-102°.
