| Popis: | 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. |
