Procedure

Under nitrogen atmosphere, 1-methyl-4-propargylpiperazine (380 mg, 2.75 mmol) was added to a degassed solution of methyl (Z)-[4-[3-(4-chlorophenyl)-3-(4-iodophenyl)-allyloxy]-2-methylphenoxy]acetate (450 mg, 0.82 mmol; prepared as described in example 7) in a mixture of tetrahydrofuran (10 mL) and triethylamine (8 mL) The solution was cooled, tetrakis(triphenylphosphine)palladium (85 mg, 0.073 mmol) and copper(I) iodide (22 mg, 0.115 mmol) were added. The reaction mixture was stirred at ambient temperature for 48 h, diluted with benzene (100 mL) and washed with water (2×50 mL). The organic solution was dried with anhydrous potassium carbonate and subsequently evaporated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, benzene/ethanol 1:0-1:2) yielding methyl (E)-[4-[3-(4-chlorophenyl)-3-[4-[3-(4-methylpiperazin-1-yl)propynyl]phenyl]-allyloxy]-2-methyl-phenoxy]acetate.
