Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C22H19N3O2, the phenol ring forms dihedral angles of 88.93 (10) and 87.95 (12)degrees with the benzimidazole system and the quinazoline benzene ring, respectively. In the crystal, molecules are linked via O-H center dot center dot center dot N hydrogen bonds into infinite chains along [100]. An intramolecular N-H center dot center dot center dot O hydrogen bond generates an S(6) ring.
