Procedure

4-Chloro-6-cyano-7-(2-methoxyethoxy)quinoline (1.7 g) and 3-fluoro-4-nitrophenol (2.0 g) were suspended in chlorobenzene (20 ml), and the suspension was heated to reflux for 6 hours. After completion of the reaction, the solvent was distilled off, ethyl acetate was added, and a solid precipitated. The solid was filtered out and washed with ether, washed with 1N sodium hydroxide water and with water, and then dried to obtain 1.55 g of the title compound.
