Abstract
In the title compound, C19H15BrN2O4S, the indole ring system is planar and the S atom has a distorted tetrahedral configuration. The dihedral angle between the sulfonyl‐bound phenyl ring and the indole ring system is 71.19 (8)°. The orientations of the phenylsulfonyl and methylpyrrolidine‐2,5‐dione substituents with respect to the indole moiety are influenced by intramolecular C—H⋯O and C—H⋯Br interactions. The pyrrolidine ring adopts an extremely flattened envelope conformation. Weak C—H⋯O interactions generate rings of motifs S(5), S(6), R21(5) and R22(9).
