In the title compound, C15H12N2O, the phenyl ring makes a dihedral angle of 32.45 (9)° with the benzene ring of the 1,5-benzodiazepin-2-one unit. The seven-membered ring adopts a boat conformation with the methylene group as the prow and the fused benzene-ring C atoms as the stern. In the crystal, inversion dimers linked by pairs of N-HO hydrogen bonds generate R22(8) loops. The dimers are further linked by C-HO hydrogen bonds, so forming a column along the a-axis direction.
