Participants

Reaction Steps

To a solution of 3-fluoro-6-iodo benzoic acid (50 g; 0.18 mol) in methanol (220 ml) were added 10 ml of sulfuric acid and the mixture heated at reflux for 24 hours. After that the solvent was evaporated and the crude mixture diluted with water and extracted with dichloromethane (3×70 ml), the organic phases were collected, washed with bicarbonate (3×100 ml), dried over sodium sulphate and concentrated to yield the desired compound (51 g).
