To a solution of 2-(2-chlorophenyl)acetonitrile (1.0 mmol), methyl benzodithioate (1.0 mmol) in DMF (2 ml), K3PO4 (2.0 mmol), pivalic acid (1.5 mmol), cuprous iodide (0.2 mmol) were added. The mixture was stirred at 80°C and progress was monitored by TLC. When the dithioesters could no longer be detected, the reaction mixture was extracted with EtOAc (3 × 10 ml). The organic layer was dried over anhydrous Na2SO4. The solvent was then removed under reduced pressure and the residue was purified by silica gel
White solid single crystals were obtained from slow evaporation of its solvent.All H atoms were positioned geometrically and allowed to ride on their parent atom, with C–H = 0.93–0.97 Å, and with Uiso(H) = 1.2–1.5Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Benzo[b]thiophene derivatives are important heterocyclic compounds because of their various applications in medicinal chemistry. They represent an important heterocyclic core and are shown to display a range of promising pharmacological properties such as antipsychotic, antidepressive, antithrombolytic, dopamine receptor antagonist and 5-lipoxygenase inhibitor. Number of 2-arylbenzo[b]thiophene derivatives have indeed, these sulfur heterocycles are essential components of clinically important drugs such as Clopidogrel (Bettinetti et al., 2002), Raloxifene (Roberts & Hartley, 2004) and Zileuton.
