Procedure
A mixture of 7-benzyloxy-4-chloro-6-methoxy-quinoline (2.04 g, 6.8 mmol), 2-fluoro-4-nitrophenol (2.34 g 14.9 mmol) and chlorobenzene (40 ml) was stirred at reflux temperature for 2 days. The reaction mixture was cooled, diluted with saturated sodium carbonate solution (30 ml) and stirred for 3 hours. The precipitate was filtered and the filtrate was separated. The aqueous layer was extracted with chloroform (3×30 ml). The organic layers were combined, washed with water and dried over sodium sulfate. The solvent was removed by evaporation under the reduced pressure. The residue was purified by column chromatography. The pure product was solidified under diisopropyl ether to give 1.11 g of product [F]. Yield: 39%.
