                                    A simple synthetic route for active metabolites of carvedilol is reported. The metabolites 4'-hydroxycarvedilol and 5'-hydroxycarvedilol have exhibited high activity for -blockade. We have disclosed syntheses of 4'-hydroxycarvedilol and 5'-hydroxycarvedilol from commercially available vanillin and isovanillin, respectively.
