Reaction Steps
Using the procedure of example 1 with the modification that methanol was used in place of ethanol, 2-[6-[4-acetyl-3-hydroxy-2-(3-phenylpropyl)phenoxy]hexyl]-6-[(6-methoxy-6-oxohexyl)oxy]benzenepropanoic acid methyl ester from the preceding example was converted into the title compound, a pale-yellow oil purified by flash-chromatography on silica gel (eluting with 3:1 toluene-ethyl acetate), in 57.4% yield.
