Abstract top

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 [pi]-[pi] 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.

Comment top

The benzimidazole core is a key building block for many biologically active compounds that play crucial roles in the function of a number of pharmacologically important molecules (Tanious et al., 2004). Substituted benzimidazoles with a wide range of activities such as antibacterial (Coburn et al., 1987) and anti-HIV (Rao et al., 2002) have been reported. As part of our ongoing structural studies of benzimidazole derivatives (Yoon et al., 2012), we now report the structure of the title compound.

In the title compound (Fig. 1), the benzimidazole ring (N1/N2/C1–C7) is planar with a maximum deviation of 0.028 (1) Å for atom N1. It makes dihedral angles of 47.69 (5) and 60.31 (5)°, respectively, with the pyridine (N3/C8–C12) and the benzene (C13–C18) rings. These two rings make a dihedral angle of 22.58 (6)° with each other. The pyrrolidine ring show a sign of envelope conformation with atom C23 at the flap, and with puckering parameters Q = 0.2695 (16) Å and φ = 81.9 (3)°.

In the crystal, the main molecule is connected to the water through O1W—H1W1···O3 and O1W—H2W1···N2i hydrogen bonds (Table 1). The molecules are further linked into a two-dimensional layer parallel to the ab plane by C14—H14A···O1Wii, C17—H17A···O2iii, C27—H27A···O2iv and C28—H28B···F1v interactions (Table 1). A ππ interaction observed between the pyridine (N3/C8–C12) and the benzene (C1–C6) rings with a centroid-centroid distance of 3.685 (8) Å (1 - x, 1/2 + y, 1/2 - z) further stabilizes the crystal structure.

Experimental top

Ethyl 3-amino-4-(3-(2-oxopyrrolidin-1-yl)propylamino)benzoate (0.84 mmol) and sodium metabisulfite adduct of 5-(4-fluorophenyl)nicotinaldehyde (1.68 mmol) were dissolved in DMF. The reaction mixture was reflux at 130 °C for 2 hrs. After completion, the reaction mixture was diluted in Ethyl acetate (20 ml) and washed with water (20 ml). The organic layer was collected, dried over Na2SO4 and the evaporated in vacuo to yield the product. The product was recrystallized from ethyl acetate.

Refinement top

H atom in water molecules were located from difference Fourier maps and freely refined. The remaining H atoms were positioned geometrically and refined using a riding model with with C—H = 0.95–0.99 Å and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms. A rotating group model was applied to the methyl group.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
