Procedure

A mixture of 3-fluoro-4-nitrobenzoic acid(2.07 g, 11.2 mmol) and cH2SO4(0.5 ml) in MeOH(10 ) was refluxed for 8 h. The solvent was evapolated. The residue was dissolved in AcOEt and washed with saturated NaHCO3 aqueous solution, water, brine, dried (Na2SO4) and concentrated to give 2.14 g(96%) of ivory solid.
