Crystal structure of 5-(5,6-di­hydro­benzo[4,5]imidazo[1,2-c]quinazolin-6-yl)-2-meth­oxy­phenol

In the mol­ecule of the title compound, C(21)H(17)N(3)O(2), the 5,6-di­hydro­benzimidazo[1,2-c]quinazoline moiety is disordered over two orientations about a pseudo-mirror plane, with a refined occupancy ratio of 0.863 (2):0.137 (2). The dihedral angles formed by the benzimidazole ring system and the benzene ring of the quinazoline group are 14.28 (5) and 4.7 (3)° for the major and minor disorder components, respectively. An intra­molecular O—H⋯O hydrogen bond is present. In the crystal, mol­ecules are linked by O—H⋯N hydrogen bonds, forming chains running parallel to [10-1].
