6.1 g of 3-acetyl-2,5-bis-(3,3-dichloroprop-2-enyloxy)-1-chlorobenzene were dissolved in 160 ml of toluene. 7.79 g of magnesium dibromide/diethyl ether complex, dissolved in 25 ml of diethyl ether, were added to this solution, and the mixture was then stirred at 85° C. for 6 hours. After the reaction had ended according to TLC, the mixture was allowed to cool, about 300 ml of water were added and the organic phase was separated off. The aqueous phase was re-extracted twice with ethyl acetate, and the combined organic phases were then washed with saturated sodium chloride solution. After drying and concentration of the organic phase, the crude product was purified chromatographically. Yield: 2.86 g (64%)
