In the title compound, C24H21NO4S, the indole ring system makes dihedral angles of 77.8 (1) and 85.4 (1)°, respectively, with the S- and C-bound phenyl rings. The molecular structure is stabilized by a weak intramolecular C—H⋯O hydrogen bond. In the crystal, a weak intermolecular C—H⋯O hydrogen bond and a C—H⋯π interaction are also observed.

To a solution of 1-phenylsulfonyl-(2-methyl-1H-indol-3-yl) (phenyl)methanol (0.5 g, 1.32 mmol) in dry DCM (20 ml) acetic anhydride (0.27 g, 2.64 mmol) and pyridine (0.2 g, 2.52 mmol) were added. It was then stirred at room temperature for 7 h under N2 atmosphere. The reaction mixture was poured over crushed ice (100 g) containing 2 ml of Conc. HCl, extracted with CHCl3 (3 × 10 ml) and dried (Na2SO4). Removal of solvent followed by recrystallization from CDCl3 afforded the compound as crystals.
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, and C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for methyl. The components of the anisotropic displacement parameters in direction of the bond of S1and O2; C3 and C4 were restrained to be equal within an effective standard deviation of 0.001 using the DELU command in SHELXL (Sheldrick, 2008).
In continuation of our studies of indole derivatives, which are known to exhibit antihepatitis B virus (Chai et al., 2006) and anti-oxidant activity (Olgen & Coban, 2003), we report the
of the title compound, (I). The bond lengths and bond angles of the title compound are agree with the reported similar structures (Chakkaravarthi et al., 2007,2008).The phenyl rings C1—C6 and C17—C22 make dihedral angles of 77.8 (1) and 85.4 (1)°, respectively, with the indole ring system. The two phenyl rings are inclined at an angle of 62.2 (1)° with respect to each other. The torsion angles C7—N1—S1—O2 and C14—N1—S1—O1 [-36.8 (2) and 51.1 (2)°, respectively] indicate a syn conformation of the sulfonyl moiety. The sum of the bond angles around N1 [351.2 (2)°] indicates that N1 is sp2-hybridized.
The molecular structure is controlled by a weak intramolecular C—H···O hydrogen bond and the crystal packing of (I) (Fig. 2) is through weak intermolecular C—H···O hydrogen bonds and C—H···π (Table 1) interactions.

In continuation of our studies of indole derivatives, which are known to exhibit antihepatitis B virus (Chai et al., 2006) and anti-oxidant activity (Olgen & Coban, 2003), we report the crystal structure of the title compound, (I). The bond lengths and bond angles of the title compound are agree with the reported similar structures (Chakkaravarthi et al., 2007,2008).
The phenyl rings C1—C6 and C17—C22 make dihedral angles of 77.8 (1) and 85.4 (1)°, respectively, with the indole ring system. The two phenyl rings are inclined at an angle of 62.2 (1)° with respect to each other. The torsion angles C7—N1—S1—O2 and C14—N1—S1—O1 [-36.8 (2) and 51.1 (2)°, respectively] indicate a syn conformation of the sulfonyl moiety. The sum of the bond angles around N1 [351.2 (2)°] indicates that N1 is sp2-hybridized.
The molecular structure is controlled by a weak intramolecular C—H···O hydrogen bond and the crystal packing of (I) (Fig. 2) is through weak intermolecular C—H···O hydrogen bonds and C—H···π (Table 1) interactions.
