Abstract: In the title compound, C10H9NO3, the dihedral angle between the benzo­furan ring system (r.m.s. deviation for the non-H atoms = 0.009 Å) and the -C-C(O)-N- segment is 83.76 (1)°. In the crystal, mol­ecules are linked by N-H...O and O-H...O hydrogen bonds, generating (001) sheets, which feature C(4) and C(10) chains.
