Versuchsvorschrift
A solution of 1-[4-(4-fluorophenoxy)phenyl]ethanone (17.7 g, 0.077 mol) in 220 ml of ethanol is cooled down to approximately 0° C. Bromine (4.8 ml, 0.096 mol) is added dropwise with a syringe. The temperature is allowed to return to ambient temperature, followed by stirring for 2 hours. After evaporation of the solvent then stirring for 10 hours in isopentane, the residue is filtered on frit and dried under a vacuum chamber bell jar. A beige-coloured powder is obtained.
