Abstract

In the title mol-ecule, C(20)H(22)N(2)O(2), the benzimidazole ring system is essentially planar, with a maximum deviation of 0.024 (1) Å. The dihedral angle between the phenyl and benzimidazole ring system is 43.71 (5)°. The atoms of the butyl group are disordered over two sets of sites with occupancies of 0.900 (4) and 0.100 (4). In the crystal structure, mol-ecules are connected by weak inter-molecular C-H⋯O hydrogen bonds, forming chains along the b axis. The crystal structure is further stabilized by C-H⋯π inter-actions.
