PROCESS FOR PRODUCTION OF N-METHIL-2,4-DINITRO-N-PHENIL-6/TRIFLUOR-METHIL/-ANILIN

摘要

The present invention provides a process for preparing N-methyl-2,4-dinitro-N-phenyl-6-(trifluoromethyl)-benzenamine comprising treating 2-chloro-3,5-dinitrobenzotrifluoride in the presence of N,N-dimethylformamide and pyridine with a fluorinating reagent to provide 2-fluoro-3,5-dinitrobenzotrifluoride, which is finally reacted with N-methylaniline.
