In the mol-ecule of the title compound, C(14)H(16)ClN(3)O, the benzene and pyrazole rings are oriented at a dihedral angle of 3.50 (3)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains. A π-π contact between the benzene and pyrazole rings [centroid-centroid distance = 3.820 (3) Å] may further stabilize the structure.
