In the title compound, C29H28N4O3, the pyrrolidine ring adopts a twist conformation whereas the oxindole and benzimidazole residues are approximately planar with maximum deviations of 0.159 (1) and 0.011 (1) Å, respectively. The oxindole residue is almost perpendicular to the benzimidazole residue, making a dihedral angle of 89.2 (1)°. The methyl-substituted benzene ring is oriented at angles of 47.7 (1) and 71.0 (1)°, respectively, with respect to the oxindole and benzimidazole residues. An intramolecular C—H⋯O hydrogen bond is observed. In the crystal, molecules associate via N—H⋯N hydrogen bonds, forming R22(9) dimers.

To a mixture of isatin (1mmol), sarcosine (1mmol) and Baylis-Hillman adduct (1mmol) was added and heated under reflux in methanol (20ml) until the disappearance of the starting materials as evidenced by TLC. The solvent was removed under vacuo. The crude product was subjected to
using petroleum ether-ethyl acetate as Single crystals were grown by slow evaporation from methanol.H atoms were placed in idealized positions and allowed to ride on their parent atoms, with C—H distances of 0.93-0.97 Å and an N—H distance of 0.86 Å, and Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C,N) for all other H atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Pyrrolidine derivatives possess anticonvulsant (Obniska et al., 2010), anti-angiogenic (Morais et al., 2009) and antitumor (Bello et al., 2010) activities. These derivatives are used as inhibitors of alpha-L-fucosidases (Moreno-Clavijo et al., 2009) and matrix metalloproteinase (Cheng et al., 2008). In view of these importance, we have undertaken the crystal structure determination of the title compound, a pyrrolidine derivative, and the results are presented here.
The molecular structure of (I) is illustrated in Fig. 1. The geometry of the pyrrolidine and oxindole residues of (I) compares well with that reported in other related structures (see, for example, Aravindan et al., 2004; Selvanayagam et al., 2005; Seshadri et al., 2003).
The sum of the angles at N1 of the pyrrolidine ring [334.8°] and N3 of the imidazole ring [359.9°] are in accordance with sp3 and sp2 hybridizations. Atom O1 is essentially coplanar with the heterocyclic ring to which it is attached, with a deviation of -0.159 (1) Å. Benzimidazole residue is planar with a maximum deviation of -0.011 (1) Å for atom C22. Atom C29 deviates 0.052 (2) Å from the best plane of the methylphenyl ring.
The dihedral angle between the oxindole and benzimidazole residues is 89.2 (1)°. This indicates that the oxindole residue is almost perpendicular to the benzimidazole residue. The methyl phenyl ring is oriented at an angles of 47.7 (1) and 71.0 (1) ° with respect to the oxindole and benzimidazole residues.
The pyrrolidine ring adopts a twist conformation, with puckering parameters (Cremer & Pople, 1975) q2 = 0.454 (1) Å and ϕ = 149.9 (2)°.
The molecular structure is influenced by an intramolecular C—H···O hydrogen bonds. Atom O1 acts as a bifurcated acceptor for two intramolecular C—H···O hydrogen bonds. In the molecular packing, N—H···N hydrogen bonds link inversion-related molecules to form R22(9) graph-set dimer (Fig.2 and Table 1).
