Abstract

Den foreliggende oppfinnelsen gjelder en ny fremgangsmåte for fremstilling av losartan, et imidazolderivat med det kjemiske navnet 2-n-butyl-4-klor-5-hydroksymetyl-l-{[2'-(1H-tetrazol-5yl)bifenyl-4]metyl}irnidazol så vel som dens farmakologisk virksomme salter. Videre gjelder oppfinnelsen nye mellomprodukter som er egnet for fremstilling av losartan og også nye fremgangsmåter for fremstilling av mellomforbindelser som er egnet for fremstilling av losartan. Et aspekt av oppfinnelsen er en fremgangsmåte for fremstilling av en forbindelse med den generelle formel (1) som kan oppstå ved fremstillingen av losartan ifølge oppfinnelsen som mellomprodukt.
