In the title compound, C(27)H(26)Br(2)N(2)O, the piperazine ring adopts a chair conformation with the N-C bonds in equatorial orientations. The C=C double bond has an E configuration. The dihedral angle between the bromo-benzene rings is 83.0 (4)°. In the crystal, inversion dimers linked through pairs of C-H⋯O hydrogen bonds generate R(2) (2)(10) loops.
