In the title compound C16H14OS the dihedral angle between the benzothio-phene ring system and the benzene ring is 72. Monoclinic = 8.0158 (6) ? = 10.8230 (9) ? = 8.1219 (6) ? β = 112.563 (4)° = 650.68 (9) ?3 = 2 Mo = 295 K 0.25 × 0.20 × 0.20 mm Data collection Bruker SMART APEXII CCD diffractometer Absorption correction: multi-scan (> 2σ(= 1.06 2946 reflections 164 parameters 2 restraints H-atom parameters constrained Δρmax = 0.35 e ??3 Δρmin = ?0.48 e ??3 Absolute structure: Flack (1983 ?) 1337 Friedel pairs Flack parameter: ?0.04 (11) Data collection: (Bruker 2004 ?); cell refinement: (Bruker 2004 ?); Ambrisentan data reduction: (Sheldrick 2008 ?); program(s) used to refine structure: (Sheldrick 2008 ?); molecular graphics: (Spek 2009 ?); software used to prepare material for publication: (-1+is usually the centroid of the ring defined by the atoms C1-C6] . Experimental To a solution of 1-(bromomethyl)-4-methoxybenzene (0.7 g 3.48 mmol) in dry 1 2 (20 ml) ZnBr2 (0.23 Ambrisentan g 1.02 mmol) and benzo[b]thiophene (0.7 g 5.22 mmol) were added. It was then stirred at room heat for 6 h under N2 atmosphere. The solvent was removed and the residue was quenched with ice-water (50 ml) made up of 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.
