In the title indole derivative, C17H15NO4S, the fused dioxolo-indole system is essentially planar [r.m.s. deviation of the 12 fitted atoms = 0.0249 Å] and is effectively perpendicular to the appended 4-tolyl ring, forming a dihedral angle of 89.95 (6)°. Overall, the mol-ecule has the shape of the letter L. In the crystal, supra-molecular layers in the ab plane are formed via weak 4-tolyl-C-H⋯π(C6-ring of indole) and S-O⋯π(1,3-dioxole) contacts. The aforementioned inter-actions along with inter-atomic H⋯H and H⋯O contacts are all shown to make significant contributions to the calculated Hirshfeld surfaces.
