Procedure

1-Propargylpyrrolidine (168 mg, 1.54 mmol) and diisopropylamine (0.27 mL, 1.93 mmol) were added to a solution of methyl (Z)-[4-[3-(4-iodophenyl)-3-[4-(5-methylthiophen-2-yl)phenyl]allyloxy]-2-methylphenoxy]acetate (235 mg, 0.385 mmol; prepared as described in example 17) in tetrahydrofuran (5 mL). The mixture was degassed and copper(I) iodide (15 mg, 0.079 mmol) and bis(triphenylphosphine)-palladium(II) dichloride (27 mg, 0.038 mmol) were added. The reaction mixture was stirred at ambient temperature for 2.5 h and subsequently evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, dichloromethane/methanol 98:2+0.5% of triethylamine) yielding methyl (E)-[2-methyl-4-[3-[4-(5-methylthiophen-2-yl)phenyl]-3-[4-[3-(pyrrolidin-1-yl)propynyl]phenyl]-allyloxy]phenoxy]acetate as brownish oil.
