In an alternative method, 4-(t-butyldimethylsilyloxy)-3-(1-adamantyl)bromobenzene (I) undergoes Suzuki coupling with 4-formylbenzeneboronic acid (II) to provide the biphenyl aldehyde (III). Subsequent Wittig condensation of (III) with methyl triphenylphosphoranylideneacetate (IV) yields the unsaturated ester (V). This is finally hydrolyzed with LiOH to furnish the title compound.
