In the title compound, C 26 H 20 BrN 3 O 3 , the central pyrrolidine ring adopts an envelope conformation. In the crystal structure, the molecules exist as centrosymmetric N-HÁ Á ÁO hydrogenbonded dimers. The dimers are linked via C-HÁ Á ÁO hydrogen bonds, forming a chain along the b axis.

The indole moiety of the title compound, C 23 H 24 N 2 O 3 , is planar; but the pyrrolidine ring adopts an envelope conformation. The conformation is stabilized by intramolecular CÐ HÁ Á ÁO interactions and the packing of the molecules is stabilized by strong NÐHÁ Á ÁN hydrogen bonds.
