Versuchsvorschrift
A mixture of 5-fluoro-2-iodo-benzoic acid (10.05 g, 39.47 mmol) and conc. H2SO4 (10 mL) in MeOH (100 ml) was reflux for 6 hours. After cooling to room temperature, NaOH (2N) was added dropwise to adjust the pH˜8. After most of organic solvent was removed under reduced pressure, the mixture was extracted with dichloromethane three times. The combined organic layers were washed with water, dried and concentrated to give the titled compound (10.80 g, yield 98%)
