Ethyl 1-sec-butyl-2-phenyl-1H-benzimidazole-5-carboxyl-ate.

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?? inter-actions.

Project description:In the title compound, C(21)H(24)N(2)O(2), the butyl group is disordered over two orientations with refined site occupancies of 0.883?(3) and 0.117?(3). The dihedral angle between the mean plane of benzimidazole ring system and the benzene ring is 39.32?(4)° and the dihedral angle between the mean plane of carboxyl-ate group and the benzimidazole ring system is 6.87?(5)°.
