Reaction Steps
5-Fluoro-2-nitrobenzenecarbonitrile (1.02 eq) and N-methylpiperazine (1.0 eq) were dissolved in NMP. Triethylamine (2.1 eq) was added, and the resulting solution heated at 100° C. for 1 hour. The solution was cooled to room temperature and poured into H2O. A precipitate formed which was filtered to yield the desired product as a green solid. LC/MS m/z 247.3 (MH+), Rt 1.46 minutes.
