title: 3-Bromo-1-(3-chloro-pyridin-2-yl)-N-(4-eth-oxy-phen-yl)-1H-pyrazole-5-carbox-amide.
abstract: In the title compound, C(17)H(14)BrClN(4)O(2), the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5 (2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloro-pyridine ring [dihedral angle = 73.7 (2)°]. An intra-molecular C-H⋯O hydrogen bond occurs. The dominant inter-action in the crystal packing is an N-H⋯N hydrogen bond, which generates a chain along the c axis. Weak inter-molecular C-H⋯O and C-H⋯N contacts are also observed.
