The asymmetric unit of the title compound, C(11)H(13)Br(1)N(2)O(1)S(1), consists of two independent mol-ecules, which are linked by N-H⋯O hydrogen bonds, forming a dimer. Both mol-ecules maintain the trans--cis configuration with respect to the position of the butanoyl groups and benzene rings against the thiono group across the C-N bonds. The mol-ecule is stabilized by intra-molecular N-H⋯O hydrogen bonds. Inter-molecular N-H⋯S, C-H⋯S and C-H⋯π inter-actions also occur.
