In the crystal, the title compound, C12H19NO2S, has a disordered structure with two equally populated conformations of the amine fragment. A pair of weak C—H⋯O inter­molecular inter­actions between the CH2 and SO2 groups gives a one-dimensional supra­molecular structure that propagates through translation along the a-axis direction.

1. Chemical context

Parasitic helminths possess a number of evolutionary strategies that facilitate their co-existence with their host and, as such, up to one third of the global population may suffer from helminthetic infections (de Silva et al., 2003[Silva, N. R. de, Brooker, S., Hotez, P. J., Montresor, A., Engels, D. & Savioli, L. (2003). Trends Parasitol. 19, 547-551.]). These parasites can secrete immunomodulatory mol­ecules that prevent the parasites' clearance from the host without leaving the host vulnerable to opportunistic infections (Hewitson et al., 2009[Hewitson, J. P., Grainger, J. R. & Maizels, R. M. (2009). Mol. Biochem. Parasitol. 167, 1-11.]). ES-62 is one such immunomodulatory mol­ecule, a protein, which was discovered in the secretions of the rodent filarial nematode Acanthocheilonema and demonstrated to induce an anti-inflammatory immunological phenotype (Harnett et al., 1989[Harnett, W., Grainger, M., Kapil, A., Worms, M. J. & Parkhouse, R. M. E. (1989). Parasitol. Today, 99, 229-239.]). ES-62 has been studied for its potential to treat human diseases relating to inflammation, for example collagen-induced arthritis or rheumatoid arthritis, and many positive outcomes have been demonstrated.

A number of the significant anti-inflammatory activities of ES-62 are associated with post-translational glycosyl­ation and subsequent esterification by phospho­rylcholine. However, ES-62 is an immunogenic protein and is thus unsuitable as a drug itself (Harnett & Harnett, 2009[Harnett, W. & Harnett, M. M. (2009). Adv. Exp. Med. Biol. 666, 88-94.]). We have sought to capitalize on the immuno­modulatory effects of ES-62 whilst avoiding its inherent undrugability through synthesizing a library of drug-like small mol­ecules based upon phospho­rylcholine, the active moiety of ES-62. A series of sulfone analogues (Fig. 1[link]) have proven to be of great significance in our investigations into collagen-induced arthritis. Despite the apparent simplicity of these mol­ecules, we are aware of no relevant crystallographic study. As such, and as the title compound is of particular inter­est to our ongoing work (Al-Riyami et al., 2013[Al-Riyami, L., Pineda, M. A., Rzepecka, J., Huggan, J. K., Khalaf, A. I., Suckling, C. J., Scott, F. J., Rodgers, D. T., Harnett, M. M. & Harnett, W. (2013). J. Med. Chem. 56, 9982-10002.]), we report herein on the solid-state structure of the title compound.

2. Structural commentary

The mol­ecular structure of the title compound is shown in Fig. 2[link]. The amine group is disordered over two equally occupied sites such that the lone pair of the pyramidal N atom is anti to O1 with respect to the plane defined by C1—S1—C9 for the conformer containing N1 but syn for the N1A conformer.

3. Supra­molecular features

Neighbouring mol­ecules related by translation along the a-axis direction are connected by two weak C—H⋯O hydrogen bonds involving O1 and C1 and C9/C9A (Table 1[link] and Fig. 3[link]). This gives one-dimensional supra­molecular chains of mol­ecules that propagate parallel to the crystallographic a-axis direction.

Other close inter­actions involve the disordered fragment. Thus the methyl group of C11A approaches the aromatic ring, giving a C—ċπ interaction [closest contact C6⋯C11A = 3.345 (5) Å] whilst C11 forms unfeasibly short inter­molecular inter­actions with its centrosymmetrically related self – an inter­action that is relieved by the observed disorder.

4. Synthesis and crystallization

A mixture of 2-[(4-methyl­benz­yl)sulfon­yl]ethyl methane­sulfonate and 1-methyl-4-[(vinyl­sulfon­yl)meth­yl]benzene (4.880 g) was dissolved in di­chloro­methane (50 ml, dry) to which di­methyl­amine (4 ml, 2M in THF) was added at room temperature with stirring. The stirring was continued at room temperature overnight. The reaction mixture was extracted with a saturated solution of sodium carbonate. The organic layer was collected, dried over MgSO4, filtered and the solvents were removed under reduced pressure and the crude product was applied to a silica gel column chromatography using first ethyl acetate/n-hexane (1/1, RF = 0.1) and then ethyl acetate/methanol (9/1). The product was obtained as a white solid which was recrystallized from ethyl acetate/n-hexane (2.200 g) (m.p. 341–343 K). HRESIMS: calculated for C12H19NO2S, 241.1136; found: 241.1139.

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. Models where the site occupancy factors of the disordered groups were allowed to refine gave occupancies equal to 50%. So in the final model, occupancies of all the disordered atoms were set to this value. The C9—C10 and C9A—C10A distances were restrained to be 1.53 (1) Å. All H atoms were placed in idealized positions and were refined in riding modes with C—H equal to 0.95, 0.98 and 0.99 Å for CH, CH2 and CH3 groups, respectively, and Uiso(H) = 1.5Ueq(C) for methyl groups and 1.2Ueq(C) for all other groups.

Experimental. 1H NMR (DMSO-d6): δ 7.28 (2H, d, J = 8.0 Hz), 7.21 (2H, d, J = 8.0 Hz), 4.44 (2H, s), 3.17 (2H, t, J = 14.3 Hz), 2.65 (2H, t, J = 14.3 Hz), 2.31 (3H, s), 2.16 (6H, s). 13C NMR (DMSO-d6): δ 137.7, 130.8, 129.0, 125.4, 58.4, 51.6, 49.0, 44.9, 20.7. IR (KBr): 1511, 1463, 1399, 1380, 1314, 1258, 1156, 1119, 1050, 892, 853, 822, 749 cm-1.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s 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 > 2σ(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.
