Versuchsvorschrift

Under the conditions of example 5 A, 1 g of 3-{6-iodo-3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-2-pyridyl}-propionic acid methyl ester is reacted with 320 mg of 3-ethinylbenzoic acid methyl ester, worked up, and the crude product is chromatographed on silica gel with hexane/0-15% ethyl acetate. 835 mg of 3-{6-[2-(3-methoxycarbonylphenyl)-ethinyl]-3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-2-pyridyl}-propionic acid methyl ester is obtained as oil.
