Procedure

A mixture of 1-ethynyl-4-trifluoromethyl-benzene (300 mg, 1.77 mmol), (4-{3-[3-bromo-5-(3-piperidin-1-yl-prop-1-ynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester (100 mg, 0.2 mmol, example 3), Pd(PPh3)4 (22 mg, 0.02 mmol), CuI (10 mg, 0.055 mmol) in dry DMF (2 ml) and triethylamine (2 ml) was heated in a microwave own for 50 min at 60° 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 ethyl acetate/methanol mixtures to give (2-methyl-4-{3-[3-(3-piperidin-1-yl-prop-1-ynyl)-5-(4-trifluoromethyl-phenylethynyl)-phenyl]-prop-2-ynyloxy}-phenoxy)-acetic acid methyl ester in 30 mg (26%) yield.
