A new one-pot synthesis of 3,4-dihydro-3-hydroxy-4-oxo-1,2,3-benzotriazine (Dhbt-OH) and derivatives directly from anthranilic acids is described. The reaction of anthranilic acids and thionyl chloride affords unstable sulfinamide anhydrides which are treated with O-(trimethylsilyl)hydroxylamine followed by diazotization to give the corresponding Dhbt-OH derivatives in good overall yield.
