Procedure
4-Bromo-2-iodo-benzoic acid (4.0 g; 12.24 mmol) is stirred in thionyl chloride (8.0 ml) under reflux for 1 hour. The reaction mixture is evaporated under reduced pressure and taken up immediately in 20 ml methylene dichloride and cooled down to 0° C. Ethanol (20.0 ml; 342.96 mmol) is added and stirred for 1 hour at ambient temperature. The ethanol is evaporated and the residue taken up in methylene dichloride and extracted with saturated NaHCO3 solution. The organic layer is separated, dried over MgSO4 and evaporated to dryness.
