Procedure
Under the conditions of example 1 D, 600 mg of 3-{3-hydroxy-6-[2-(4-methoxycarbonylmethylphenyl)-ethinyl]-2-pyridyl}-propionic acid methyl ester is reacted with 460 mg of (1E)-6-bromo-1-(4-methoxyphenyl)-1-hexene, worked up, and the crude product is chromatographed on silica gel with hexane/0-10% ethyl acetate. 504 mg of 3-{3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-6-[2-(4-methoxycarbonylmethylphenyl)-ethinyl]-2-pyridyl}-propionic acid methyl ester is obtained as oil.
