The title compound, C(14)H(11)BrClNO, consists of chloro-benzene and bromo-benzene units which are linked at either end of the N-methyl-propionamide group. The chloro-benzene unit [maximum deviation = 0.005 (4) Å] makes a dihedral angle of 68.21 (19)° with the bromo-benzene unit [maximum deviation = 0.012 (3) Å]. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains along [010].
