In the title compound, C27H24Cl2N2O3, 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-methyl-pyrrolidine ring, which adopts an envelope conformation with the N atom at the flap position. The mol-ecular structure is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) and S(7) ring motifs, and an intra-molecular π-π inter-action involving the benzyl and di-chloro-substituted benzene rings [centroid-centroid distance = 3.6291 (11) Å]. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming C(7) chains running parallel to [10-1].
在标题化合物C₂₇H₂₄Cl₂N₂O₃中，吲哚环系基本呈平面状，羰基C原子的最大偏差为0.082 (2) Å。它与4-甲基吡咯烷环的平均平面形成88.53 (6)°的二面角，该吡咯烷环呈信封构象，N原子位于折边位置。分子结构通过分子内C—H⋯O氢键得以稳定，这些氢键产生S(6)和S(7)环模式，以及涉及苄基和二氯取代苯环的分子内π-π相互作用[质心-质心距离 = 3.6291 (11) Å]。在晶体中，分子通过N—H⋯O氢键相连，形成平行于[10-1]的C(7)链。
