In the title compound, C21H17N3O3, the dihydroquinazoline ring adopts a screw-boat conformation and its stereogenic C atom has anSconfiguration. The dihedral angle between the mean planes of the two hydroxyphenyl rings is 86.61 (12)°. The amino H atom forms an intramolecular hydrogen bond with a phenol O atom, while the hydrazine N atom acts as an acceptor for the H atom of the other phenol group. In the crystal, O—H...N and O—H...O hydrogen bonds and weak C—H...centroid(π-ring) intermolecular interactions are observed, forming chains along [1-10] and [110].
