실험 절차

A solution of methyl (Z)-[2-methyl-4-[3-(4-iodophenyl)-3-(4-methylphenyl]allyloxy]-phenoxy]acetate (310 mg, 0.587 mmol; example 3) in a mixture of tetrahydrofuran (9 mL) and triethylamine (9 mL) was degassed and 1-propargyl-1H-pyrazole (124 mg, 1.17 mmol) was added in argon atmosphere. The solution was cooled down; tetrakis(triphenylphosphine)palladium (54 mg, 0.046 mmol) and copper(I) iodide (17.8 mg, 0.094 mmol) were added. The reaction mixture was stirred at ambient temperature for 4 days, subsequently evaporated in vacuo and the residue was dissolved in ethyl acetate (20 mL). The solution was washed with water (3×15 mL), dried with anhydrous magnesium sulphate and evaporated in vacuo. The residue was purified by flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 7:3) yielding methyl (Z)-[2-methyl-4-[3-(4-methylphenyl)-3-[4-(3-pyrazol-1-ylpropynyl)phenyl]allyloxy]phenoxy]acetate.
