Ethyl 1-sec-butyl-2-(2-hydroxyphenyl)-1H-benzimidazole-5-carboxylate 0.25-hydrate

In the title compound, C20H22N2O3·0.25H2O, the water molecule (occupancy 0.25) is disordered across a crystallographic inversion center. The dihedral angle between the hydroxyphenyl ring and the benzimidazole ring system is 59.31 (9)°. In the crystal structure, molecules are connected by intermolecular O—H...N and C—H...O hydrogen bonds. The crystal structure is further stabilized by a weak C—H...π interaction involving the imidazole ring
