A class of substituted 1,2,3-benzotriazines are obtained in tandem mode reaction by means of Cu-catalyzed intramolecular C-H activation of aniline, isocyanides and dialkyl azadicarboxylate in acetonitrile at room temperature in good yields. The speed and ease of carrying out this three-component reaction under mild one-pot conditions with available materials, without using column chromatography, make
