Reaction Steps

3-Butyryl-4-(2-methylphenylamino)-8-hydroxyquinoline (3.2 g, 10 mmol) and potassium t-butoxide (5.0 g, 40 mmol) were stirred in dry dimethylformamide at 80° and 2-dimethylaminoethyl chloride hydrochloride (2.9 g, 20 mmol) added. The mixture was stirred for 2 hours, poured into water and extracted with ether. The extracts were dried and evaporated. Chromatography (silica gel, 3-5% methanolic ammonia in dichloromethane) and recrystallisation from ether gave 3-butyryl-4-(2-methylphenylamino)-8-(2-dimethylaminoethoxy)quinoline (1.0 g, 34%), m.p. 88°-90°.
