چکیده
The crystal structure of the title compound, C(21)H(19)N(5)O(3), is stabilized by inter-molecular N-H⋯N and C-H⋯O hydrogen bonds. The mol-ecule contains a planar [maximum deviations = -0.026 (1) and 0.027 (2) Å] benzofuran ring system, which forms dihedral angles of 78.75 (8) and 39.78 (7)° with the benzene and triazole rings, respectively.
