Abstract
Se revela un procedimiento para la elaboracion del maleato de flupirtina puro, (maleato de la 2-amino-3-etoxicarbonilamino-6-(p-fluorobencilamino)piridina), como también de su modificacion cristalina A, mediante hidrogenacion del 2-amino-3-nitro-6-(4-fluorbencilamino)-piridina(ANFP) en presencia de níquel de Raney, acilacion con éster etílico de ácido cloro-formico y la transformacion de la base de flupirtina obtenida conácido maleico, en el cual la hidrogenacion, laacilacion y la precipitacion se efectuan en alcoholes hidrosolubles.Se revela además la modificacioncristalina A de dicho compuesto. El maleato de flupirtina es util como analgésico.
