A FACILE PREPARATION OF PHTHALIMIDES AND A NEW APPROACH TO THE SYNTHESIS OF INDOPROFEN VIA CARBONYLATION

This report describes an improved synthesis of a heterocyclic propionic acid, 2-4(1-oxo-2isoindolinyl) phenyl propionic acid, Indoprofen (I) via carbonylation, a potent anti-inflammatory agent and an analgesic. The synthesis highlights the preparation of Indoprofen starting from readily available o-toluic acid and p-amino acetophenone by a sequence of reactions that included oxidative addition of carbonylation.
