necessary to perform oxidations of the pyridine and pyrazine moieties. Generally, it was found that direct oxidation with OXONE® gave efficient preparation of pyrazine dioxides. Oxidation with dimethyldioxirane was used to preclude problems associated with the isolation of particularly hydrophilic pyrazine and pyrazine-/V-oxides. In this work we describe the convenient and efficient synthesis of oxygenated
