Abstract

Un procedimiento para la preparación del yoduro de 2-(2- furoil)¿1,4-dimetilpiridinio de fórmula I. **(Fórmula)** caracterizado porque en una primera etapa de síntesis se hace reaccionar bajo atmósfera de nitrógeno, la 2-ciano-4- metilpiridina con una disolución etérea de 2-furil-litio recientemente preparado, y porque tras de una hidrólisis ácida se obtiene la 2-(2-furoil)-4-metilpiridina (II). **(Fórmula)** la cual por calentamiento en presencia de un halógenuro de metilo, por ejemplo el ioduro de metilo, se convierte en el compuesto de fórmula I.
