Two metabolites of a free radical scavenger, edaravone, were synthesized. Edaravone glucuronate was synthesized by glycosylation of a glucuronic acid precursor using silver (I) trifluoromethane-sulfonate with edaravone. Edaravone sulfate was synthesized by sulfonylation of edaravone using a sulfur trioxide-pyridine complex. The two synthesized metabolites were identical to isolated metabolites. X-ray analysis identified edaravone glucuronate as β-O-glucuronate, although there were three possible edaravone glucuronate tautomers.
