title: 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.
