In the title mol-ecule, C(14)H(11)N(3)O, the benzene ring is twisted by 14.0 (2)° from the plane through the fused ring system. In the crystal, π-π inter-actions [centroid-centroid distances = 3.609 (1), 3.639 (1) and 3.735 (1) Å] form stacks of mol-ecules propagating along the b axis. The crystal packing is further stabilized by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.
