A mixture of 0.25 g of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 0.195 g of 4-chloro-2-fluoro-5-hydroxyaniline, 0.116 g of pyridine hydrochloride, and 3 ml of ethoxyethanol was stirred under nitrogen, at reflux temperature for 1 h. The mixture was cooled and added to 10 ml of water. To this mixture was added sodium carbonate until pH 9. The product was collected, washed with water, and dried to give 0.327 g of 4-(4-chloro-2-fluoro-5-hydroxy-phenylamino)-6,7-dimethoxy-quinoline-3-carbonitrile as a solid, dec >260° C. ; mass spectrum (electrospray, m/e): M+H 373.9.
