Abstract
Reaction of 6-nitro-7-oxo-4,7-dihydroazolo[5,1-c][1,2,4]triazines with methyl iodide or dimethyl sulfate affords the N-methyl derivatives, no O-alkylation products being found. The effect of the alkylating agent, solvent, and the azole moiety on the course of the reaction has been examined.
