In the title compound, C(18)H(14)Br(2)N(2)O(3), an intra-molecular N-H⋯N hydrogen bond forms an eight-membered ring. The dihedral angle between the planes of the quinoline system and the benzene ring is 41.69 (1)°. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds and short Br⋯O inter-actions [3.0079 (19) Å].
