Abstract
In the molecule of the title compound, C21H18N4O3, the fused pyrrolo[3,4-c]pyrazole ring system is approximately planar [maximum deviation = 0.0486 (16) Å] and forms dihedral angles of 87.21 (8) and 35.46 (7)° with the phenyl rings. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds and weak C—H⋯π interactions link the molecules into chains parallel to [201].
