The invention relates to a method of preparing an ester of an aromatic carboxylic acid bearing at least one perfluoroalkyl group on the aromatic ring and, more specifically, alkyl esters with low carbon condensation. The inventive method is characterised in that it consists in (i) reacting an aromatic compound bearing at least one perfluoroalkyl group and at least one nitrile group on the aromatic ring, an alkanol and a strong protonic acid at a temperature of at least 45° C. and (ii) recovering the ester thus produced.
