The method of Example 16 was repeated using a Grignard reagent, prepared from 3-phenoxyphenyl bromide (0.19 g), tetrahydrofuran (2 ml) and magnesium (22 g), and 4-(4-chlorophenyl)-2-fluoro-4-methylpent-2-enyl acetate (Example 13) (0.12 g). The residue after evaporation was purified by preparative thin layer chromatography (solvent: diethyl ether/hexane; 1:9) and then preparative high performance liquid chromatography (column: C18; solvent: methanol; flow rate: 3 ml/min; to give the title compound (38 mg, 22%).
