In the title molecule, C20H22N2O2, the benzimidazole ring system is essentially planar, with a maximum deviation of 0.024 (1) A ˚ . 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 struc
