In the title compound, C 27 H 24 Cl 2 N 2 O 3 , the indole ring system is essentially planar, with a maximum deviation of 0.082 (2) Å for the carbonyl C atom. It makes a dihedral angle of 88.53 (6)° with the mean plane of the 4-methylpyrrolidine ring, which adopts an envelope conformation with the N atom at the flap position. The molecular structure is stabilized by intramolecular C—H...O hydrogen bonds, which generate S (6) and S (7) ring motifs, and an intramolecular π–π interaction involving the benzyl and dichloro-substituted benzene rings [centroid–centroid distance = 3.6291 (11) Å]. In the crystal, molecules are linked via N—H...O hydrogen bonds, forming C (7) chains running parallel to [10-1].
