Summary:Preparation of a hydroxybenzoic acid benzyl ester, comprises the acid-catalysed reaction of a dibenzyl ether (and optionally a benzyl alcohol) with an alkyl- or alkoxy-carbonyloxybenzoic acid. Preparation of a hydroxybenzoic acid benzyl ester of formula (I), comprises the acid-catalysed reaction of a dibenzyl ether of formula (II) (and optionally a benzyl alcohol of formula (III)) with an alkyl- or alkoxy-carbonyloxybenzoic acid of formula (IV); R -R = 1-6C alkyl, alkoxy, haloalkyl or haloalkoxy, CN, CO(1-6C alkyl), NO2 or halogen; and R = H or optionally unsaturated and optionally halogenated 1-50C alkyl, aralkyl, aryl, alkoxy, aralkoxy or aryloxy.
