  • Patent number: 6559308
    Abstract: The present invention relates to a method for preparing quinoxaline-5- and 6-carboxylic acids. The method comprises contacting an aqueous suspension of a 5- or 6-hydroxymethyl quinoxaline with oxygen in the presence of a transition metal catalyst, to form the respective quinoxaline-5- or 6-carboxylic acid. The method for oxidizing benzylic methyl groups may also be employed to prepare a wide variety of heterocyclic carboxylic acid compounds.
