1) The oxidation of tasosartan (V) with KMnO4 and NaOH in water gives metabolite (I). 2) The condensation of tasosartan (V) with 2,3,4-tri-O-acetyl-1alpha-bromo-1-deoxy-D-glucopyranosyluronic acid methyl ester (VI) by means of KOH in refluxing acetone gives the acetylated glucuronide methyl ester (VII), which is deacetylated with KCN in methanol yielding glucuronide methyl ester (VIII). Finally, this compound is hydrolyzed with NaOH in methanol to afford metabolite (II).
