Procedure
2.0 g of 2-(3-chloro-propyl)-2-(4-fluoro-phenyl)-[1,3]dioxolane are added to a suspension of 2.36 g of 2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenol, 1.7 g of potassium carbonate and 120 mg of potassium iodide in 50 ml of acetone. The mixture is then stirred for 48 hours at 60° C. The reaction mixture is concentrated and the residue is taken up in water and extracted with ethyl acetate. After concentration of the organic phase and purification over silica gel, 2-{3-[2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenoxy]-propyl}-2-(4-fluoro-phenyl)-[1,3]dioxolane is obtained.
