Article abstract of DOI:10.1055/s-1997-1283

Reaction of 1-fluoro-2-nitrobenzene or 1,2-dinitrobenzene with guanidine in hot THF followed by treatment with potassium tert-butoxide gave 3-amino-1,2,4-benzotriazine 1-oxide in good yield, which was further oxidized by peracetic acid to afford the title compound.
