Abstract
Some 3-aryl-7,8-dimethoxy-1,2,3-benzotriazin-4-(3H)-ones (3a-g) were prepared in moderate to good yield by nitrosation of N-aryl-2-amino-3,4-dimethoxybenzanilides (2a-g). The latter were obtained by hydrazine hydrate graphite reduction of corresponding N-aryl-2-nitro-3 4-dimethoxybenzanilides (1a-i). The IR of these compounds have been discussed.
