Versuchsvorschrift

2-Ethynyl-5-methylthiophene (176 mg, 1.442 mmol) and diisopropylamine (0.475 mL, 3.39 mmol) were added to a solution of methyl (E)-[4-[3-(4-iodophenyl)-3-(3-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate (420 mg, 0.721 mmol; prepared as described in example 34) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (11.0 mg, 0.0576 mmol) and bis(triphenylphosphine)palladium(II) dichloride (25.3 mg, 0.0361 mmol) were added. The reaction mixture was stirred at ambient temperature for 20 h and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 19:1) yielding methyl (E)-[2-methyl-4-[3-[4-[(5-methylthiophen-2-yl)ethynyl]phenyl]-3-(3-trifluoromethylphenyl)allyloxy]phenoxy]acetate as yellow oil.
