The asymmetric unit of the title compound, C(13)H(20)N(4)O(4), contains two crystallographically independent mol-ecules in which the dihedral angles between the fused pyrrole and pyrazole rings are 5.06 (8) and 1.12 (8)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds into chains parallel to the b axis. ...[more]
