To a well stirred suspension of sodium hydride (0.27 g, 5.62 mmol) in dry tetrahydrofuron (15 ml) at room temperature, a solution of diethyl malonate (1.4 ml, 9.47 mmol) in dry tetrahydrofuron (10 ml) was slowly added over a period of 20 min. After the evolution of hydrogen gas ceased, a solution of ethyl-1-phenyl sulfonyl-2-bromo methyl indole-3-carboxylate (2 g, 4.73 mmol) in dry THF (20 ml) was added in dropwise with vigorous stirring. Then the reaction mixture was stirred for 3 h. The reaction mixture was quenched with ice containing few drop of concentrated HCl, extracted with dichloro methane (3 X 5 ml) and dried (Na2SO4). The solvent was removed under vacuum. Then the crude product was purified by column chromatography on siliga gel (hexane-ethyl acetate 9:1). Single crystals suitable for X-ray analysis were grown by slow evaporation of ethyl acetate solution at room temperature.
The site occupancy factors for disordered C and O atoms were refined as C22 = 0.25 (2), C22A = 0.75 (2), C25 = 0.134 (10), C25A = 0.866 (10), C17 = 0.36 (2), C17A = 0.64 (2), O3 = 0.43 (6) and O3A = 0.57 (6) during anisotropic refinement. The distances C16—C17, C21—C22, C21—C22A, C24—C25 and C24—C25A were restrained to 1.55 (1) Å; the bond distances C24—C25/C24—C25A and C21—C22/C21—C22A were restrained to be equal within 0.02 Å and the non-bonding distances O6—C25/O6—C25A and O8—C22/O8—C22A were restrained to be equal within 0.04 Å. H atoms were positioned geometrically and refined using riding model with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic C—H, C—H = 0.98 Å and Uiso(H) = 1.2Ueq(C) for C—H, C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2 and C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for CH3.

Benzenesulfonamide derivatives exhibit significant biological activities, such as antibacterial (Nieto et al., 2005), anticancer and anti - HIV (Pomarnacka & Kozlarska-Kedra, 2003) and antitumor (Yang et al., 2002). Sulfur containing compounds mostly act as simple narcotics (Schultz et al., 2001).
Geometric parameters in the title compound (Fig. 1) agree with the reported values of similar structures (Chakkaravarthi et al., 2007; Liu et al., 2007). The sum of the bond angles around N1 (358.19°) indicates sp2 hybridization.
The torsion angles C14—N1—S1—O1 and C7—N1—S1—O2 [-54.54 (17)° and 13.62 (2)°, respectively] indicate the syn conformation of the sulfonyl moiety with indole ring system.
The molecular structure is stabilized by weak intramolecular C - H···O interactions (Table 1). A similar compound with ethoxycarbonyl group has been reported (Chakkaravarthi et al., 2007).
