The complete mol-ecule of the title compound, C(20)H(19)Br(2)NO, is generated by crystallographic mirror symmetry, with two C, one O and one N atom lying on the mirror plane. The compound exists in a twin-chair conformation with equatorial dispositions of the 3-bromo-phenyl groups [dihedral angle between rings = 27.37 (3)°]. The packing is stabilized by weak N-H⋯O and C-H⋯O inter-actions.
