title: Ethyl 1-(butan-2-yl)-2-(2-meth-oxy-phen-yl)-1H-benzimidazole-5-carboxyl-ate.
abstract: In the title compound, C(21)H(24)N(2)O(3), the mean planes of the benzene ring and the benzimidazole ring system form a dihedral angle of 69.94 (7)°. The ethyl group atoms of the ethano-ate fragment are disordered over two sets of sites, with refined occupancies of 0.742 (6) and 0.258 (6). In the crystal, there are weak C-H⋯N hydrogen bonds which connect mol-ecules into chains along the b axis. A weak inter-molecular C-H⋯π inter-action is also observed.
