2-Fluoro-5-iodo-3-nitro-benzoic acid (2.0 g, 6.43 mmol) and SOCl2 (918 mg, 7.72 mmol) were added to 20 mL MeOH, and the mixture was refluxed for two hours and then cooled to room temperature. Solvent was evaporated under reduced pressure and the residue was dissolved in EtOAa. The EtOAc slolution was washed with brine, dried over NasSO4, filtered and concentrated under reduced pressure to give 2.0 g (96%) of 2-fluoro-5-iodo-3-nitro-benzoic acid methyl ester.
