Reaction Steps
A solution of 5-fluoro-2-nitrobenzonitrile (60 g, 354 mmol), (3,5-difluorophenyl)methanol (52.14 mL, 460 mmol) and cesium carbonate (155 g, 460 mmol) in dry DMF (720 mL) was stirred at 70° C. for 6 hours. The reaction mixture was cooled at room temperature and poured into water (7 L) under stirring. The so obtained precipitated was filtered, washed with water and dried under vacuum at 50° C., affording 95 g (yield 92%) of the title compound.
