Versuchsvorschrift
A solution of 1-(5-chloro-4-fluoro-2-hydroxyphenyl)ethanone (23.8 g, 126 mmol) in acetic acid (100 mL) was treated with N-iodosuccinimide (34.1 g, 151 mmol) and stirred at 70° C. for 2 hours. The reaction mixture was concentrated, diluted with EtOAc and quenched with sat. NaHCO3 solution. The organic layer was separated, washed with water, dried over MgSO4 and concentrated under reduced pressure to give the desired product to be used in the next step without further purification.
