3-Butyryl-4-(2-methylphenylamino)8-hydroxyquinoline → HCID 10388048, compound

Participants

Reaction Steps

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 dimethylformamide (100 ml) at 100° , 1-(3-chloropropyl)pyrrolidine hydrochloride (3.6 g, 20 mmol) added, and stirring continued for 1 hour. The mixture was diluted with water and extracted with ether, and the ether extracts dried and evaporated. Chromatography (silica gel, 0-3% methanolic ammonia in chloroform) and recrystallisation from ether gave 3-butyryl-4-(2-methylphenylamino)-8-(3-(1-pyrrolidinyl)propoxy)quinoline (0.35 g, 8.5 %), m.p. 101°-103°.
