Friedel-Crafts condensation of 4-bromophenol (I) with 1-adamantanol (II) in the presence of H₂SO₄ yielded the adamantyl phenol (III). Subsequent alkylation of the sodium phenoxide of (III) with iodomethane produced the methyl ether (IV). The Grignard reagent (V), prepared from aryl bromide (IV), was converted to the organozincate derivative, and then subjected to a nickel-catalyzed cross-coupling with methyl 6-bromo-2-naphthoate (VI) to furnish adduct (VII). The target carboxylic acid was finally obtained by saponification of the methyl ester (VII).
