2-Anilino-3-(2-hy-droxy-phen-yl)quinazolin-4(3H)-one methanol monosolvate.

In the title compound, C20H15N3O2·CH3OH, the quinazolin­one ring system is approximately planar, the dihedral angle between the pyrimidinone ring and the adjacent benzene ring being 1.73 (6)°. The pyrimidinone ring makes dihedral angles of 77.58 (6) and 29.62 (6)°, respectively, with the hy­droxy­phenyl and phenyl rings. In the crystal, the components are connected by O—H⋯O and C—H⋯O hydrogen bonds, forming a zigzag chain along the b axis.
