Versuchsvorschrift

1-Propargylpyrazole (0.530 g, 5.0 mmol) and diisopropylamine (1.6 mL, 11.7 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-methylsulfanylphenyl)allyloxy]-2-methylphenoxy]acetate (1.40 g, 2.5 mmol; prepared as described in example 40) in tetrahydrofuran (35 mL). The mixture was degassed and copper(I) iodide (38.0 mg, 0.2 mmol) and bis(triphenylphosphine)palladium(II) dichloride (87.5 mg, 0.12 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 7:3) yielding methyl (E)-[2-methyl-4-[3-(4-methylsulfanylphenyl)-3-[4-[3-(pyrazol-1-yl)propynyl]phenyl]allyloxy]-phenoxy]acetate as yellow oil.
