Procedure

To a solution of 3-cyano-4-fluoronitrobenzene (0.530 g, 3.19 mmol) and N-(2-fluoro-5-hydroxyphenyl)-2-[3-(trifluoromethyl)phenyl]acetamide (1.00 g, 3.19 mmol) in N,N-dimethylformamide (5 mL) was added potassium carbonate (0.530 g, 3.83 mmol), and the mixture was stirred at room temperature for 4 hr. The reaction mixture was diluted with ethyl acetate (100 mL), washed successively with water (100 mL) and saturated brine (100 mL), and dried over anhydrous magnesium sulfate. Insoluble material was filtered off. The obtained organic layer was purified by basic silica gel column chromatography (eluate: 50% ethyl acetate/n-hexane), and the obtained solution was concentrated under reduced pressure to give the title compound (1.38 g, 94%) as a yellow oil.
