Reaction Steps

Under the conditions of example 1 D, 490 mg of 5-[3-hydroxy-2-(2-methoxycarbonylethyl)-6-pyridyl]-pentanoic acid methyl ester is reacted with 365 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. 293 mg of 5-{2-(2-methoxycarbonylethyl)-3-[6-(4-methoxyphenyl)-(5E)-5-hexenyloxy]-6-pyridyl}-pentanoic acid methyl ester is obtained as oil.
