In the title compound, C29H29BrN2O3, the indole ring system is essentially planar (r.m.s. deviation = 0.079 Å) and makes a dihedral angle of 85.23 (10)° with the mean plane of the 4-methyl-pyrrolidine ring. This ring adopts an envelope conformation with the N atom at the flap. The pyrrolidine ring of the indole ring system adopts a twisted conformation on the C-C(=O) bond. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(14) ring motif. These dimers are further linked by N-H⋯O and C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (10-1).
在标题化合物C29H29BrN2O3中，吲哚环系统基本呈平面状（均方根偏差 = 0.079 Å），与4-甲基-吡咯烷环的平均平面形成85.23 (10)°的二面角。该环呈信封构象，N原子位于折边上。吲哚环系统的吡咯烷环在C-C(=O)键上呈扭曲构象。分子结构通过分子内C-H⋯O氢键得以稳定，该氢键形成一个S(6)环模式。在晶体中，分子通过成对的C-H⋯O氢键相连，形成具有R 2 (2)(14)环模式的反演二聚体。这些二聚体通过N-H⋯O和C-H⋯O氢键进一步相连，形成平行于(10-1)的二维网络。
