3-(4-Bromo-phen-yl)-4-(4-hy-droxy-anilino)furan-2(5H)-one.

ABSTRACT: In the title compound, C(16)H(12)BrNO(3), the butyrolactone core adopts the furan-2(5H)-one structure and forms dihedral angles of 44.80 (17) and 65.73 (18)° with the bromo-benzene and phenol rings, respectively. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (3)(26) loops The edge-fused rings extend to form a chain running along the b-axis direction and C-H⋯π contacts help to consolidate the packing.
