Procedure

5.0 mL of conc. HNO3 at 0° C. was slowly treated with 10.0 mL of conc. H2SO4, then 3.52 g (20.0 mmol) of 3,4,5-trifluoro-benzoic acid. The reaction mixture was warmed up to room temperature and stirred overnight. The mixture was poured into a beaker containing ice. The resulting solid was collected by filtration, washed with cold water and dried to produce 3.4 g (16.0 mmol, 80%) of 2-nitro-3,4,5-trifluoro-benzoic acid. LCMS: 222 (M+1)+.
