Versuchsvorschrift

6.0 g (27.5 mmol) of 3,5-difluoro-2-nitro-benzoic acid methyl ester was dissolved in DMF and treated with 2.9 g (30.25 mmol) of ammonium carbonate. The reaction was heated at 60° C. for 6 h. Water was added to the reaction mixture. The solid produced was collected by filtration and washed with water to produce 3-amino-5-fluoro-2-nitro-benzoic acid methyl ester. LCMS: 215 (M+1)+.
