Abstract:
In the title compound, C(12)H(13)N(3)O(2), the dihedral angle between the pyrazole and benzene rings is 50.0 (3)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds to form a three-dimensional network. Two weak C-H⋯π inter-actions reinforce the crystal packing.
