RESUMEN
In the title compound, C(22)H(17)NO(3)S, the N atom of the indole ring system deviates by 0.031â (3)â Å from a least-squares plane fitted through all nine non-H ring atoms.

RESUMEN
The asymmetric unit of the title compound, C(21)H(15)NO(3)S, contains two crystallographically independent mol-ecules.
