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 [100].

The title compound, C11H10BrNO3, is close to planar with the benzofuran unit and the ester group subtending a dihedral angle of 5.25 (2)°. The molecular structure features an intramolecular N—HO interaction. In the crystal, N—HO hydrogen bonds involving carboxyl O-atom acceptors generate a chain extending along [201].
