Ethyl 2-(3,4-dimethoxybenzyl)-1-phenylsulfonyl-1H-indole-3-carboxylate

In the title compound, C26H25NO6S, the phenyl ring forms a dihedral angle of 82.5 (1)° with the indole ring system. The molecular structure is stabilized by weak intramolecular C—H⋯O interactions and the crystal structure is stabilized by weak intermolecular C—H⋯O interactions.

The chemistry of indole has been of increasing interest, since several compounds of this type possess diverse biological activities (Macor et al., 1992). In addition, phenylsulfonyl indole compounds inhibit the HIV-1 RT enzyme in vitro and HTLVIIIb viral spread in MT-4 human T-lymphoid cells (Williams et al., 1993).
The widening of the angles may be due to repulsive interactions between the two short S=O bonds.

Refinement
H atoms were positioned geometrically and refined using riding model with C-H = 0.93Å and U iso (H) = 1.2Ueq(C) for aromatic C-H, C-H = 0.97Å and U iso (H) = 1.2Ueq(C) for CH 2 , C-H = 0.96Å and U iso (H) = 1.5Ueq(C) for CH 3 .
