(Received 19 May 2010; accepted 20 May 2010; online 26 May 2010)

In the title compound, C16H14OS, the dihedral angle between the benzothio­phene ring system and the benzene ring is 72.41 (12)°. A weak inter­molecular C—H⋯π inter­action from the benzene ring to the benzothio­phene ring system is observed in the crystal structure.

Supporting information


Comment top

Thiophene derivatives exhibit anti-HIV PR inhibitors (Bonini et al., 2005) and anti-breast cancer (Brault et al., 2005) activities. In addition, some of the benzo[b]thiophene derivatives shows significant antimicrobial and anti-inflammatory activities (Isloora et al., 2010).

The geometric parameters of the title molecule (Fig. 1) agree well with reported similar structures (Gunasekaran et al., 2009; Umadevi et al., 2009). The dihedral angle between the two benzene rings is 71.93 (8)°. The C1—S1 and C8—S1 bond distances are 1.738 (3) and 1.734 (3) Å respectively, which are comparable to the literature value of 1.712 (2) Å (Allen et al., 1987).

The crystal packing is stabilized by a weak C—H···π interaction [C14—H14···Cg (-1+x, y, -1+z), Table 1; Cg is the centroid of the ring defined by the atoms C1—C6] .

Experimental top

To a solution of 1-(bromomethyl)-4-methoxybenzene (0.7 g, 3.48 mmol) in dry 1,2-dichloroethane (20 ml) ZnBr2 (0.23 g, 1.02 mmol) and benzo[b]thiophene (0.7 g, 5.22 mmol) were added. It was then stirred at room temperature for 6 h under N2 atmosphere. The solvent was removed and the residue was quenched with ice-water (50 ml) containing 1 ml of conc. HCl, extracted with chloroform (2 × 10 ml) and dried (Na2SO4). Removal of solvent followed by column chromatographic purification (n-hexane/ethyl acetate 94:6) afforded the product as a colourless crystal.

Refinement top

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 = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2, C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for CH3.
