Water → N-(3,5-difluorophenyl)-3,5-difluoro-2-nitroaniline

Participants

Reaction Steps

To a solution of 2,4,6-trifluoronitrobenzene (1.37 g, 7.74 mmol) and 3,5 difluoroaniline (1 g, 7.74 mmol) in THF (23 mL) was added potassium tert-butoxide (1.3 g, 11.6 mmol) and reaction mixture was stirred at rt for 4 h. After completion of the reaction, water (50 mL) was added and the organic phase extracted with EtOAc (200 mL), dried over sodium sulfate and purified by column chromatography using 100-200 mesh silica gel and 0-10% EtOAc in hexane to provide N-(3,5-difluorophenyl)-3,5-difluoro-2-nitroaniline: LC-MS (ESI) m/z 284.9 [M+H]+.
