Reaction Steps

To a solution of 1.0 g (6.37 mmol) of 2,4,6-trifluorobenzonitrile in MeOH (25 mL) was added 0.6 mL (6.9 mmol) of morpholine and 1.2 mL (6.7 mmol) of N,N-diisopropylethylamine. The mixture was heated to 50° C. for 6 h then cooled to room temperature and diluted with H2O which caused a solid to precipitate from solution. The white solid was collected by filtration, washed with H2O and dried under vacuum to provide 0.98 g (68%) of 2,6-difluoro-4-morpholin-4-yl-benzonitrile as a white solid.
