Abstract
An improved method of producing 3-amino-1,2,4-benzotriazines using nitrobenzene or a derivative thereof, a guanidine salt and a base as reactants is provided. The method is carried out at a moderate reaction temperature without producing halide wastes derived from nucleophilic substitution and acid byproducts.
Claims1
A method of producing a 3-amino-1,2,4-benzotriazine compound comprising combining nitrobenzene or a derivative thereof with a guanidine salt in the presence of a base at a moderate reaction temperature to produce a 3-amino-1,2,4-benzotriazine.
