The mixed acid nitration ot 2-aminopyridines gives 2-nitramino pyridines in good yields. Since these nitramino pyridines can theoretically exist in two tautomeric forms, the possibility of isolating the alkyl derivatives of these forms was undertaken. Compounds such as 2-nitramino pyridine, 2-nitramino-4-methyl pyridine and a new compound 2-nitramino-4, 6-dimethyl-3(5)-nitro pyridine were allowed to react with diazomethane, diazoethane and diazopropane and the products isolated.
