In the title mol­ecule, C 19 H 18 Br 4 N 2 O 2 , the dihedral angle between the benzene rings is 73.9 (2)°. Two intra­molecular N—H⋯O hydrogen bonds make  S (6) ring motifs. In the crystal, mol­ecules are linked  via  C—H⋯O inter­actions, forming chains propagating along the  a -axis directon. A short C⋯Br [3.401 (5) Å] contact is present in the crystal structure, which is further stabilized by a π–π inter­action [centroid–centroid distance = 3.739 (3) Å].
