synthesized which contain a tertiary N at the 4 position. These materials were obtained by reacting 4-nitro-2-picoline N-oxide, either directly or after conversion to the corresponding 4-chloro derivative, with a variety of secondary amines. Rearrangement of the 4-substituted 2-picoline N-oxides with Ac2O yielded respective methyl acetates, which upon acid hydrolysis, MnO2 oxidation, and reaction with
