title: Diethyl 2-[(5-meth-oxy-2-methyl-1-phenyl-sulfonyl-1H-indol-3-yl)methyl-ene]malonate.
abstract: In the title compound, C(24)H(25)NO(7)S, the sulfonyl-bound phenyl ring is approximately perpendicular to the indole ring system [dihedral angle = 87.72 (5)°]. The methyl group of one of the ester units is disordered over two positions with occupancies of 0.527 (13) and 0.473 (13). An intra-molecular C-H⋯O hydrogen bond is observed. In the crystal structure, mol-ecules are linked into a ribbon structure running along the c axis by inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions involving the pyrrole ring.
