Acetonitrile → HCID 59820929, compound

Participants

Reaction Steps

A mixture of 5-fluoro-2-nitro-4′-(trifluoromethoxy)biphenyl (compound of Example 78(1)) (700 mg, 2.32 mmol), diethylamine (339 mg, 4.64 mmol), potassium carbonate (320 mg, 2.32 mmol) and acetonitrile (5 ml) was stirred at 100° for 10 hours under argon atmosphere. The reaction mixture was cooled to room temperature, diluted with water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. The residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel (n-hexane:ethyl acetate=10:1) to give the title compound (580 mg, 70.5%) as a yellow solid.
