摘要：

In the title compound, C23H22N2O4S, the pyrrolidine ring has an envelope conformation with the spiro C atom, shared with the indoline ring system, as the flap. The mean planes of the benzothiophene and indoline ring systems are inclined to the mean plane of the pyrrolidine ring by 88.81 (8) and 79.48 (8)degrees, respectively, and to each other by 68.12 (5)degrees. In the crystal, molecules are linked via C-H center dot center dot center dot O hydrogen bonds, forming chains propagating along [001].
