In the structure of the title compound, C20H16N4·CH4O, the aniline ring forms dihedral angles of 89.9 (2) and 85.4 (2)° with the benzimidazole and benzene rings, respectively. The orientation of the aniline ring is mainly determined by strong hydrogen bonds between the amino group and the non-fused quinazoline N atom. Intermolecular hydrogen bonds of the N—H...N—H...N type along [010] and the N—H...O—H...N type along [100] are formed, resulting in C22(4) and C22(10) descriptors, respectively, on a binary level of graph-set analysis. There are C—H...π contacts with H...π distances of 2.44 Å; however, no π-stacking is observed.
