Procedure

110 g (0.38 mole) of 1-(4-chlorophenoxy)-5-chloro-3-ethyl-3-methyl-2-pentanone are dissolved in 400 ml of chloroform. 60.8 g (0.38 mole) of bromine are added dropwise at room temperature such that the solution is always decolorized. The reaction mixture is then subsequently stirred at room temperature for 30 minutes and concentrated by distilling off the solvent. 138.5 g (99% of theory) of 1-bromo-1-(4-chlorophenoxy)-5-chloro-3-ethyl-3-methyl-2-pentanone of refractive index nD20 1.5250 are obtained. ##STR100##
