An improved process for the preparation of pioglitazone and its pharmaceutically acceptable salts by reducing 5-[4-[2-(5-ethyl-2-pyridyl)ethoxy]benzilidene]-2,4-thiazolidinedione with sodium borohydride in presence of a cobalt ion and dimethyl glyoxime. More particularly the cobalt ion used is cobalt chloride hexahydrate, or, cobalt (II) nitrate hexahydrate in presence of mixture of DMF and water as solvents.
Methods of preparation of API pioglitazone were discussed from the point of view of impurities occurrence. Four real impurities (I–IV) of pioglitazone were prepared and characterized by means of NMR spectroscopy.
