Abstract: 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-HN-HN type along [010] and the N-HO-HN 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 contacts with H distances of 2.44 Å; however, no -stacking is observed.
