Versuchsvorschrift
2-Fluoro-6-methylbenzoic acid (40 g, 0.26 mol) was dissolved in 320 mL of sulfuric acid and chilled to −15° C. To this was added 14 mL of fuming nitric acid in 60 mL of sulfuric acid over a 10 minute period. Once the addition was complete, the mixture was stirred at 0° C. for 1 hour, then poured into ice water, and stirred. The resulting solids were collected and then dissolved in EtOAc, which was washed with water, dried over sodium sulfate and concentrated to 50 g (97%) of the title compound.
