Versuchsvorschrift

To a stirred solution of 2-bromo-5-iodobenzoic acid (25.0 g, 76.48 mmol) in dichloromethane (200 mL) was added oxalylchloride (10.3 mL, 114.74 mmol) at 0° C. followed by DMF (0.9 mL). After complete addition, the reaction mixture was stirred at room temperature for 3 h. Volatiles were evaporated under reduced pressure to furnish 2-bromo-5-iodo-benzoyl chloride (26.4 g). The crude product was used for the next step immediately.
