Reaction Steps

A solution of 630 mg of 7-methoxycarbonyl-3-{[6-(4-methoxyphenyl)-5-hexenyl]oxy}-9-oxo-9H-xanthene-4-propanic acid ethyl ester in ethyl acetate was hydrogenated in the presence of 10 mg of 5% palladium on carbon. After hydrogen uptake ceased, the solution was filtered, concentrated in vacuo, and the residue crystallized from ethyl acetate/hexane to provide 580 mg of the desired subtitle intermediate, m.p. 108°-109° C.
