The title compound, C(14)H(13)N(5), crystallizes with two crystallographically independent mol-ecules in the unit cell. The two mol-ecules form dimers through inter-molecular N-H⋯N and C-H⋯N hydrogen bonds. The hydrogen-bonding motifs are R(2) (2)(8) for both the N-H⋯N and C-H⋯N inter-actions. The pyrazole and pyrimidine rings form dihedral angles of 6.2 (3) and 8.3 (3)° with each other and the dihedral angles between the pyrazole and benzene rings are 54.9 (2) and 58.6 (2)°. The benzene rings of neighbouring dimers also exhibit C-H⋯π inter-actions.
