実験手順
4.64 g (20 mmol) of 3,5-difluoro-2-nitro-benzoic acid ethyl ester in DMF and 2.1 g (22 mmol) of ammonium carbonate was heated at 60° C. for 6 h. The reaction mixture was treated with water. The resulting solid was collected by filtration and washed with water to produce 3.4 g (15.0 mmol, 75%) of 3-amino-5-fluoro-2-nitro-benzoic acid ethyl ester. LCMS: 229 (M+1)+.
