Ethyl 1-sec-butyl-2-(4-chloro-phen-yl)-1H-benzimidazole-5-carboxyl-ate.

ABSTRACT: In the title compound, C(20)H(21)ClN(2)O(2), the ethyl 1H-benzimidazole-5-carboxyl-ate ring system, excluding the methyl-ene and methyl H atoms, is almost planar, with a maximum deviation of 0.055?(1)?Å, and makes a dihedral angle of 40.63?(4)° with the benzene ring. The sec-butyl group is disordered over two positions, with refined site occupancies of 0.855?(4) and 0.145?(4). In the crystal, mol-ecules are linked into chains along [010] via inter-molecular C-H?O hydrogen bonds and are further inter-connected by C-H?Cl inter-actions into two-dimensional networks parallel to (001). The crystal structure is further consolidated by C-H?? inter-actions.
