Ethyl 2-[5-(4-fluorophenyl)pyridin-3-yl]-1-[3-(2-oxopyrrolidin-1-yl)propyl]-1H-benzimidazole-5-carboxylate

Abstract

In the title compound, C28H27FN4O3·H2O, the benzimidazole ring system is essentially planar with a maximum deviation of 0.028 (1) Å. It makes dihedral angles of 47.59 (5) and 60.31 (5)°, respectively, with the pyridine and benzene rings, which make a dihedral angle of 22.58 (6)° with each other. The pyrrolidine ring shows an envelope conformation with one of the methyl­ene C atoms as the flap. In the crystal, the components are connected into a tape along the b-axis direction through O—H⋯O and O—H⋯N hydrogen bonds and a π–π inter­action between the pyridine and benzene rings [centroid–centroid distance of 3.685 (8) Å]. The tapes are further linked into layers parallel to the ab plane by C—H⋯O and C—H⋯F inter­actions.
