실험 절차

A mixture of 1-ethynyl-4-trifluoromethyl-benzene (149 mg, 0.88 mmol), {4-[3-(3,5-dibromo-phenyl)-prop-2-ynyloxy]-2-methyl-phenoxy}-acetic acid methyl ester (412 mg, 0.88 mmol, intermediate 2), Pd(PPh3)2Cl2 (101 mg, 0.088 mmol), CuI (46 mg, 0.246 mmol) in dry DMF (2 ml) and triethylamine (2 ml) was heated in a microwave own for 20 min. at 75° C. in a sealed tube. The reaction mixture was filtered through Decalite and the filtrate was evaporated. The residue was purified on column chromatography using methylene chloride/heptanes mixtures to give (4-{3-[3-bromo-5-(4-trifluoromethyl-phenylethynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester in 94 mg (19%) yield.
