Abstract

Un proceso para producir fomesafeno a partir de acifluorfeno que incluye los pasos de a) convertir acifluorfeno a su cloruro de acilo, b) acoplar el cloruro de acilo así formado con metansulfonamida para formar fomesafeno crudo y c) purificar el fomesafeno crudo, caracterizado porque cada uno de los pasos se lleva a cabo en un único solvente en común, que es preferiblemente un cloroalcano. Preferiblemente se condensan los pasos en uno de modo que no hay aislación del producto para ningún paso hasta que se obtiene el fomesafeno.
