PROCESS FOR THE PREPARATION OF BOSENTAN

The present invention provides a novel process for obtaining Bosentan, with few synthesis steps, by coupling the intermediate pyrimidine compound of formula I with the sulfonamide compound of formula II. The use of said efficient process prevents the use of hazardous chemicals and thus it is of considerable interest for obtaining Bosentan in a large industrial scale. The invention also refers to the novel intermediates of formula II and to a process for its production.
