2-{2-[3-(1H-Benzimidazol-2-yl)quinolin-2-yloxy]ethoxy}ethanol

Abstract

In the title compound, C20H19N3O3, the interplanar angle between the benzimidazole unit and the quinoline unit is 25.1 (2)°. Two different hydrogen bonds involving the hydroxy group and the imidazole unit are present. An intramolecular N—H...O hydrogen bond links the hydroxy group of the side chain with the imidazole unit, forming a 12-membered ring, and an intermolecular O—H...N hydrogen bond links the molecules, forming chains in the crystallographic b direction.
