Procedure

4-Hydroxy-1-propargylpiperidine (171 mg, 1.23 mmol) and diisopropylamine (0.40 mL, 2.85 mmol) were added to a solution of the methyl (Z)-[4-[3-(4-tert-butylphenyl)-3-(4-iodohenyl)allyloxy]-2-methylphenoxy]acetate (350 mg, 0.614 mmol; prepared as described in example 30) in tetrahydrofuran (10 mL). The mixture was degassed and copper(I) iodide (10 mg, 0.053 mmol) and bis(triphenylphosphine)palladium(II) dichloride (22 mg, 0.031 mmol) were added. The reaction mixture was stirred at ambient temperature over night, filtered and the filtrate was evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 97:3) yielding methyl (Z)-[4-[3-(4-tert-butyl phenyl]-3-[4-[3-(4-hydroxypiperidin-1-yl)propynyl]phenyl]allyloxy]-2-methylphenoxy]-acetate as white solid.
