Methyl 3-[(1H-benzimidazol-1-yl)meth-yl]-1-methyl-4-(4-methyl-phen-yl)-2'-oxopyrrolidine-2-spiro-3'-1-benzimidazole-3-carboxyl-ate.

ABSTRACT: In the title compound, C(29)H(28)N(4)O(3), 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 intra-molecular C-H?O hydrogen bond is observed. In the crystal, mol-ecules associate via N-H?N hydrogen bonds, forming R(2) (2)(9) dimers.
