Reaktionsschritte

A mixture of 1-prop-2-ynyl-piperidine (53 mg, 0.44 mmol), {4-[3-(3,5-dibromo-phenyl)-prop-2-ynyloxy]-2-methyl-phenoxy}-acetic acid methyl ester (204 mg, 0.44 mmol, intermediate 2), Pd(PPh3)4 (50 mg, 0.044 mmol), CuI (23 mg, 0.12 mmol) in dry DMF (2 ml) and triethylamine (2 ml) was heated in a microwave own for 30 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 (4-{3-[3-bromo-5-(3-piperidin-1-yl-prop-1-ynyl)-phenyl]-prop-2-ynyloxy}-2-methyl-phenoxy)-acetic acid methyl ester in 105 mg (47%) yield.
