The method of Example 25 was repeated using a Grignard reagent, prepared from 3-phenoxyphenyl bromide (2.35 g), tetrahydrofuran (10 ml) and magnesium (0.21 g) and 1-(3-acetoxy-2-fluoroprop-1-enyl)-1-(4-ethoxyphenyl)cyclopropane (Example 18) (0.6 g). The residue after evaporation was purified by column chromatography (solvent: diethyl ether/hexane; 5:95) to afford 1-(4-ethoxy-phenyl)-1-(2-fluoro-3-(3-phenoxyphenyl)prop-1-enyl)cyclopropane (0.34 g, 41%)
