Procedure

2.0 g (9.9 mmol) of 2,6-difluoro-3-nitro-benzoic acid in methanol and 3.0 g (30.0 mmol) of ammonium acetate was stirred at room temperature for 12 h. The solvent was evaporated and dilute HCl solution was added. The precipitated solid was collected by filtration and washed with water to produce 2-amino-6-fluoro-3-nitro-benzoic acid. LCMS: 201 (M+1)+.
