Versuchsvorschrift

To a stirred mixture 2,6-difluorophenylacetonitrile (3.06 g, 20.0 mmol) in 30 mL of H2SO4 at 0° C. was added 12 mL of a 1:1 mixture of nitric acid and sulfuric acid. The reaction mixture stirred for 5 h and poured onto crushed ice. The resulting solid was filtered and air dried to give 2,6-difluoro-3-nitro-phenylacetamide.
