Versuchsvorschrift

1-Propargylpiperidin-4-ol (191 mg, 1.374 mmol) and diisopropylamine (0.45 mL, 3.23 mmol) were added to a solution of methyl (E)-[4-[3-(4-iodophenyl)-3-(3-trifluoromethylphenyl)-allyloxy]-2-methylphenoxy]acetate (400 mg, 0.687 mmol; prepared as described in example 34) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (10.4 mg, 0.055 mmol) and bis(triphenylphosphine)palladium(II) dichloride (24.1 mg, 0.034 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, chloroform/methanol 96:4) yielding methyl (E)-[4-[3-[4-[3-(4-hydroxypiperidin-1-yl)propynyl]phenyl]-3-(3-trifluoromethylphenyl)allyloxy]-2-methylphenoxy]acetate as yellow oil.
