• In the title compound, C16H16BrNO4, the dihedral between the planes of the aromatic rings is 7.74 (18)°. The amide group is tilted with respect to the bromo- and methoxy-substituted aromatic rings by 36.3 (8) and 35.2 (8)°, respectively. The meta-methoxy groups are essentially in-plane with the aromatic ring [dihedral angles CH3-O-C-C = -4.6 (4) and -2.5 (4)°]. The para-methoxy group is markedly displaced from the ring plane [dihedral angle CH3-O-C-C = -72.5 (4)°]. The crystal packing is stabilized by N-H...O hydrogen bonds linking the molecules into chains running along the b axis. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.004 Å; R factor = 0.033; wR factor = 0.076; data-to-parameter ratio = 14.6.
