Versuchsvorschrift
Bromine (4.96 g, 31.1 mmol) was slowly added dropwise to a solution of 1-(2,3-difluorophenyl)ethanone (4.85 g, 31.1 mmol) in diethyl ether (100 ml), and the mixture was stirred at room temperature for 5 hours. The reaction mixture was distilled off under reduced pressure to give 7.29 g (99.9%) of the desired product as an oil.
