In the title compound, C(17)H(14)BrClN(4)O(2), the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5â
(2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloro-pyridine ring [dihedral angle = 73.7â
(2)°]. An intra-molecular C-Hâ¯O hydrogen bond occurs. The dominant inter-action in the crystal packing is an N-Hâ¯N hydrogen bond, which generates a chain along the c axis. Weak inter-molecular C-Hâ¯O and C-Hâ¯N contacts are also observed.
