Procedure

A mixture of 1.24 g of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 1.61 g of 3-trifluoromethylaniline, 0.4 ml of pyridine, and 15 ml of ethoxyethanol was stirred, under nitrogen, at reflux temperature for 5 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 1.34 g of 4-[(3-trifluoromethylphenyl)amino]-6,7-dimethoxy-3-quinolinecarbonitrile as a solid, mp 190-193° C.
