Procedure

1-Propargylpiperidin-4-ol (154 mg, 1.10 mmol) was added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-[4-(trifluoromethyl-sulfanyl)phenyl]allyloxy]-2-methylphenoxy]-acetate (340 mg, 0.553 mmol; prepared as described in example 56) and diisopropylamine (0.35 mL, 2.49 mmol) in tetrahydrofuran (9 mL). The mixture was degassed and copper(I) iodide (8.4 mg, 0.044 mmol) and bis(triphenylphosphine)palladium(II) dichloride (19.3 mg, 0.027 mmol) were added. The reaction mixture was stirred under argon at ambient temperature for 20 h, filtered and the filtrate was evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, chloroform/methanol 97:3) yielding methyl (E)-[4-[3-[4-[3-(4-hydroxypiperidin-1-yl)propynyl]phenyl]-3-[4-(trifluoromethylsulfanyl)phenyl]-allyloxy]-2-methylphenoxy]acetate.
