Abstract: The present invention relates to a novel process for the production of [2-(4-fluoro-benzyl)-phenyl]-acetic acid, a compound obtainable from phthalic anhydride. The process comprises the subsequent steps a) through e): a) reacting phthalic anhydride with fluorobenzene or a derivative thereof in appropriate reaction conditions; b) over reducing the product obtained in step a) at the ketone moiety; c) reducing the product obtained in step b) with sodium dihydro-bis(2-methoxyethoxy)aluminate (Red-Al) to the corresponding alcohol; d) chlorinating the alcohol obtained in step c); e) inserting CO into the product obtained in step d) through an appropriate Pd-containing catalytic system. In an alternative embodiment, the step e) is replaced by the steps f1) and f2): f1) reacting the product obtained in step d) with sodium cyanide; f2) hydrolysing the product obtained in step f1).
