(Received 28 March 2013; accepted 9 April 2013; online 13 April 2013)

In the title compound, C17H15BrO2S, the 4-methyl­benzene ring makes a dihedral angle of 89.01 (7)° with the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzo­furan fragment. In the crystal, mol­ecules are linked into supra­molecular layers that stack along [001] by weak C—H⋯O, C—H⋯π and C—S⋯π [3.364 (2) Å] inter­actions.

Comment top

As a part of our continuing study of 5-bromo-2,7-dimethyl-1-benzofuran derivatives containing 4-fluorophenylsulfinyl (Choi et al., 2011a) and 4-cyclohexylsulfinyl (Choi et al., 2011b) substituents in the 3-position, we report herein the crystal structure of the title compound.

In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.013 (2) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angle between the 4-methylbenzene ring and the mean plane of the benzofuran ring is 89.01 (7)°. In the crystal structure (Fig. 2), molecules are connected by weak C–H···O and C–H···π interactions (Table 1, Cg is the centroid of the C11-C16 4-methylphenyl ring), and by intermolecular C–S···π interactions between the sulfur atom and the 4-methylphenyl ring of an adjacent molecule, with a S1···Cgiii being 3.364 (2) Å.

Experimental top

3-Chloroperoxybenzoic acid (77%, 224 mg, 1.0 mmol) was added in small portions to a stirred solution of 5-bromo-2,7-dimethyl-3-(4-methylphenylsulfanyl)-1-benzofuran (302 mg, 0.9 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 4 h, the mixture was washed with saturated sodium bicarbonate solution and the organic layer was separated, dried over magnesium sulfate, filtered and concentrated at reduced pressure. The residue was purified by column chromatography (hexane-ethyl acetate, 1:1 v/v) to afford the title compound as a colourless solid [yield 79%, M.pt: 406-407 K; Rf = 0.63 (hexane-ethyl acetate, 1:1 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of its acetone solution held at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C–H = 0.95 Å for aryl and 0.98 Å for methyl H atoms. Uiso(H) = 1.2Ueq(C) for aryl and 1.5Ueq(C) for methyl H atoms. The positions of methyl hydrogens were optimized rotationally.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) 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.
