Conditions

Temperature: 130 °C

Procedure

7-(Benzyloxy)-4-chloro-6-methoxyquinoline (300 mg) and 3-fluoro-4-nitrophenol (785 mg) were dissolved in chlorobenzene (3 ml), and the solution was stirred at 130° C. for 5 hr. Chloroform and an aqueous sodium hydroxide solution were added to the reaction solution, and the mixture was stirred for one hr. The reaction solution was extracted with chloroform, and the chloroform layer was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by thin-layer chromatography on silica gel by development with hexane/ethyl acetate (1/1) to give 197 mg (yield 47%) of the title compound.
