(Received 23 May 2013; accepted 29 May 2013; online 8 June 2013)

In the title compound, C21H21FO2S, the cyclo­hexyl ring adopts a chair conformation. The 3-fluoro­phenyl ring makes a dihedral angle of 83.16 (4)° with the mean plane [r.m.s. deviation = 0.005 (1) Å] of the benzo­furan ring system. In the crystal, mol­ecules are linked by pairs of C—H⋯π inter­actions into inversion dimers, which are further packed into stacks along the a-axis direction by C—H⋯π inter­actions.

Comment top

As a part of our continuing study of 5-cyclohexyl-2-methyl-1-benzofuran derivatives containing phenylsulfinyl (Choi et al., 2011), 4-bromophenylsulfinyl (Choi et al., 2012a) and 4-methylphenylsulfinyl (Choi et al., 2012b)substituents in 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 0.005 (1) Å from the least-squares plane defined by the nine constituent atoms. The cyclohexyl ring has the chair form. The dihedral angle between the 3-fluorophenyl ring and the mean plane of the benzofuran ring system is 83.16 (4)°. In the crystal structure (Fig. 2), molecules are connected by pairs of C—H···π interactions into dimers, which are further packed into stacks along the a axis by C—H···π interactions (Table 1, Cg1 and Cg2 are the centroids of the C1/C2/C7/O1/C8 furan ring and the C2–C7 benzene ring, respectively).

Experimental top

3-Chloroperoxybenzoic acid (77%, 202 mg, 0.9 mmol) was added in small portions to a stirred solution of 5-cyclohexyl-3-(3-fluorophenylsulfanyl)-2-methyl-1-benzofuran (272 mg, 0.9 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 4h, 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, 4:1 v/v) to afford the title compound as a colorless solid [yield 68%, m.p. 403–404 K; Rf = 0.43 (hexane-ethyl acetate, 4:1 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in ethyl acetate 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, 1.00 Å for methine, 0.99 Å for methylene and 0.98 Å for methyl H atoms, respectively. Uiso(H) = 1.2Ueq(C) for aryl, methine and methylene, and 1.5Ueq(C) for methyl H atoms. The positions of methyl hydrogens were optimized rotationally.

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.
