In the title compound, C(12)H(15)BrN(2)O(2), the dihedral angle between the benzene ring and the mean plane of the amide grouping is 77.7 (8)°. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur, and the packing is further supported by C-H⋯O and C-H⋯Br inter-actions and weak π-π ring stacking inter-actions.
