Application of 50594-78-0, These common heterocyclic compound, 50594-78-0, name is 5-Fluoro-2-nitrobenzonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
5-(4-Methylpiperazinyl)-2-nitrobenzenecarbonitrile 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.
Statistics shows that 5-Fluoro-2-nitrobenzonitrile is playing an increasingly important role. we look forward to future research findings about 50594-78-0.
