Abstract

In the title compound, C(32)H(33)NO(6)S, the indole ring system makes dihedral angles of 62.78 (10) and 80.53 (8)°, respectively, with the phenyl and benzene rings. In the crystal, the mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. Between the chains, a weak aromatic π-π stacking inter-action [centroid-centroid distance = 3.831 (2) Å] is observed.
