Ethyl 1-tert-butyl-2-(4-hydr-oxy-3-methoxy-phen-yl)-1H-benzimidazole-5-carboxyl-ate
Abstract:
In the title compound, C(21)H(24)N(2)O(4), the benzimidazole ring system is almost planar, with a maximum deviation of 0.047 (1) Å and makes a dihedral angle of 88.44 (5)° with the attached benzene ring. In the crystal, mol-ecules form infinite chains along the b axis by way of inter-molecular O-H⋯N and C-H⋯O inter-actions. Weak C-H⋯π also contribute to the stabilization of the crystal structure.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
