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—HN 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—HO and C—HF interactions.
