The title compound, C15H13N3O2, crystallizes with two independent mol-ecules in the asymmetric unit, which differ considerably in the dihedral angles made between the phenyl groups and the five-membered rings [47.19 (8) and 61.16 (9)° in one mol-ecule and 55.04 (10) and 55.00 (8)° in the other]. In the crystal, N-H⋯O hydrogen bonds generate columnar units having approximate fourfold rotational symmetry about axes parallel to b.
标题化合物C15H13N3O2在不对称单元中以两个独立分子结晶，这两个分子中苯基与五元环之间形成的二面角差异很大[一个分子中为47.19 (8)和61.16 (9)°，另一个分子中为55.04 (10)和55.00 (8)°]。在晶体中，N—H⋯O氢键形成了沿平行于b轴具有近似四重旋转对称性的柱状单元。
