In the title compound, C17H19N3O, the benzotriazole ring is essentially planar, with a maximum deviation of 0.0069 (15) Å. The mean plane of the benzotriazole ring forms a dihedral angle of 13.16 (4)° with the mean plane of the benzene ring. The crystal packing is stabilized by [pi]-[pi] stacking interactions, with a centroid-centroid distance of 3.8077 (12) Å, together with weak C-H...[pi] interactions. Molecules are stacked along the a axis.
