title: 4-[(3-Oxo-1,3-dihydro-2-benzofuran-1-yl)amino]-benzoic acid.
abstract: In the title compound, C(15)H(11)NO(4), the dihedral angle formed by the benzene ring and the essentially planar 2-benzofuran ring system is 55.93 (3)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link pairs of mol-ecules, generating centrosymmetric R(2) (2)(8) ring motifs. These dimeric units are connected via N-H⋯O hydrogen bonds, forming C(6) chains along [100].
