Abstract

New procedure for the preparation of ethyl apovincaminoate. It involves: reacting apovincaminic acid (II) with ethanol in the presence of a catalyst of formula (III), in which X = -OCH3, -COCH3, -NO2, -CH3 and -CN. The reaction is carried out in an organic polar solvent, in the presence of an organic base and at ambient temperature. Ethyl apovincaminoate (I) has application in the treatment of cerebral disorders and in geriatrics. <IMAGE>
