Abstract
In the title compound, C20H17BrN2O2, the seven-membered oxepine ring adopts a chair conformation. The indole moiety is essentially planar with a maximum deviation of 0.031 (3)Å. The indole ring system forms a dihedral angle of 21.87 (8)° with the mean plane of the 10-membered heterobicycle. The crystal packing is stabilized by intermolecular C—H⋯O and C—H⋯π interactions.
