A five-step synthesis of deuterium-labelled diclofenac starting from 2-phenyl[2H5] acetic acid is described. The synthesis prevents deuterium from scrambling during the reaction. It offers the labelled compound with over 99% isotopic enrichment. It also provides a possible alternative route for the synthesis of deuterium-labelled 4′-hydroxydiclofenac, which is the principal human metabolite of diclofenac.
