In the title mol-ecule, C(11)H(14)BrNO, there is twist between the mean plane of the amide group and the benzene ring [C(=O)-N-C C torsion angle = -31.2 (5)°]. In the crystal, inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonds link mol-ecules into chains along [100]. The methyl group H atoms are disordered over two sets of sites with equal occupancy.
