A novel solid-phase synthesis of thalidomide has been described: The coupling of phthalic anhydride (I) with hydroxymethyl polystyrene resin (II) by means of triethylamine and 4-dimethylaminopyridine (DMAP) in DMF affords the resin-linked acid (III), which is then condensed with alpha-aminoglutarimide (IV) by means of diisopropylcarbodiimide (DIC) and N-hydroxybenzotriazole (HOBt) in DMF to provide amide (V). Finally, thalidomide is obtained by treatment of resin (V) with TFA in refluxing toluene.
