Procedure

A mixture of 1.00 g of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 0.89 g of 3-fluoroaniline, 0.32 ml of pyridine, and 12 ml of ethoxyethanol was stirred at reflux temperature for 4 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 to give a solid, mp 226-230° C.
