analyses, and provided insight into the reaction mechanism. Preparation of pyridine N-oxide amine 4 was accomplished via a selective oxidation of the corresponding pyridinylamine 6. Pyridinylthioimidate 27 was prepared from pyrazinone 7 via a two-step one-pot process in near quantitative yield. Chlorination of the pyrazinone ring in 3 followed by hydrolysis and amide coupling completed the synthesis of
