実験手順

1-Propargylpiperidin-4-ol (0.401 g, 2.88 mmol) and diisopropylamine (1.6 mL, 11.73 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-[4-(methylsulfanyl)phenyl]allyloxy]-2-methylphenoxy]acetate (1.40 g, 2.5 mmol; prepared as described in example 40) in tetrahydrofuran (12 mL) and triethylamine (12 mL). The mixture was degassed and copper(I) iodide (49.0 mg, 0.256 mmol) and tetrakis(triphenylphosphine)palladium (148 g, 0.128 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 97:3) yielding methyl (E)-[4-[3-[4-[3-(4-hydroxypiperidin-1-yl)propynyl]phenyl]-3-[4-(methylsulfanyl)phenyl]-allyloxy]-2-methylphenoxy]acetate as yellow oil.
