Participants

Reaction Steps

A mixture of 0.86 g of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 0.86 g of N-methylaniline, 0.32 ml of pyridine, and 12 ml of ethoxyethanol was stirred, under nitrogen, at reflux temperature for 24 h. The mixture was cooled and partitioned with dichloromethane and aqueous sodium bicarbonate. The organic layer was washed with water, dried and evaporated. The residue was recrystallized from ethyl acetate-hexanes to give 0.54 g of 4-[(methylphenyl)amino]-6,7-dimethoxy-3-quinolinecarbonitrile as a solid, mp 137-141° C.
