Versuchsvorschrift
5-Fluoro-2-(2,2,2-trifluoroacetamido) benzoic acid (140; 1.29 g, 5.1 mmol) was added, in small portions, to fuming nitric acid (7 mL) at 0° C. The resulting reaction mixture was stirred at 0° C. for 1 hand then poured into ice-water (10 mL). The resulting precipitate was collected by filtration, washed with water and dried to afford 5-fluoro-3-nitro-2-(2,2,2-trifluoroacetamido)benzoic acid 141 (1.2 g, 80%).
