실험 절차

1-Propargylpyrazol (500 mg, 4.7 mmol) was added under nitrogen atmosphere to a degassed solution of methyl (Z)-[4-[3-(4-chlorophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (680 mg, 1.24 mmol; example 15) in a mixture of tetrahydrofuran (10 mL) and triethylamine (10 mL). The solution was cooled, tetrakis(triphenylphosphine)palladium (118 mg, 0.1 mmol) and copper(I) iodide (38 mg, 0.2 mmol) were added. The reaction mixture was stirred at ambient temperature for 48 h, diluted with benzene (100 mL) and the resulting mixture was washed with water (2×50 mL). The organic solution was dried with anhydrous potassium carbonate and subsequently evaporated in vacuo. The residue was purifled by column chromatography (silica gel Fluka 60, benzene-chloroform/ether 2:1) yielding methyl (E)-[4-[3-(4-chlorophenyl)-3-[4-[3-(pyrazol-1-yl)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetate.
