详细

Diazotization of aminopyridines upon treatment with NaNO2 and H3PO4 in acetonitrile led to the formation of N-pyridinylacetamides. This reaction constitutes a convenient and general preparative method for the synthesis of 2-, 3-, and 4-N-pyridinylacetamides under mild conditions in good yields. The in situ oxidation of the thus obtained N-pyridinylacetamides with hydrogen peroxide gave good yields of pyridinylacetamide N-oxides.
