실험 절차

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 384 mg of 4-ethinylbenzoic acid methyl ester, worked up, and the crude product is chromatographed on silica gel with hexane/0-7% ethyl acetate. 670 mg of 3-{6-[2-(4-methoxycarbonylphenyl)-ethinyl]-3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-2-pyridyl}-propionic acid methyl ester is obtained as oil.
