In the title compound, C14H14BrNO5, the ester group is disordered [occupancy ratio 0.52 (2):0.48 (2)]. The major component is nearly coplanar with the benzofuran plane, subtending a dihedral angle of 7.84 (2)°, while the amide group is twisted out of the benzofuran plane making a dihedral angle of 39.69 (2)°. An intramolecular N-HO hydrogen bond occurs. In the crystal, pairs of weak C-HO hydrogen bonds link the molecules into inversion dimers, which are further linked via strong N-HO hydrogen bonds, generating a zigzag chain extending along .
