Abstract

Den foreliggende oppfinnelsen angår en fremgangsmåte for fremstillingen av irbesartan eller dets farmasøytisk akseptable salter, som omfatter en syntese av tritylirbesartan ved en reaksjon mellom 5-(4-brommetyl)bifenyl-2-yl)-1-(trifenylmetyl)tetrazol og 2-n-butyl-4-syklopentan-2-imidazolin-5-on eller et salt av disse, i et organisk løsemiddel i nærvær av en faseoverføringskatalysator og en base, en fjerning av den beskyttende gruppen og en isolering av irbesartan eller dets farmasøytisk akseptable salt.
