The title compound, C13H19NO2S, was synthesized by the reaction of N-cyclohexylaminebenzenesulfonamide and methyl iodide. The crystal packing is stabilized by weak intermolecular C—H⋯O hydrogen bonds.

Sodium hydride (0.88 mmol) was taken in a round bottom flask and washed with n-hexane so as to remove the mineral oil dispersant. A solution of N-cyclohexylamine benzene sulfonamide (0.43 mmol) in 5 ml of N,N dimethyl formamide was added. The mixture was stirred for half an hour at room temperature. Then, methyl iodide (0.86 mmol) was added and stirring was continued for about 3 hrs until the complete consumption of sulfonamide. The reaction was monitored by TLC. After the completion of the reaction the contents were transferred into the distilled water ice. The product precipitated and was separated by filtration and recrystallized from methanol. The melting point of the product was observed to be 353 K uncorrected.
All H atoms were placed in calculated positions and refined using a riding model [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms; C—H = 0.98 Å and Uiso(H) = 1.2Ueq(C) for tertiary CH; C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2; C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for the methyl H atoms]. The final difference Fourier map had a highest peak at 0.71 Å from atom C1 and a deepest hole at 0.71 A Å from atom S1, but were otherwise featureless.
Sulfonamide compounds have gained much importance due to their therapeutic applications. The compound containing cyclohexylamine has been reported to be an activator of dopamine receptors in the CNS (Hacksell et al., 1981). The title compound is a sulfonamide derivative of cyclohexylamine in continuation to our previous work (Arshad et al., 2008; Arshad et al., 2009).
The molecular structure of the title compound (I) is shown in Fig. 1. The mean plane of the benzene ring and that of the four essentially planar C atoms (C8, C9, C11, C12. Maximum deviation, 0.0132 Å) of the chair-form cyclohexyl ring have a dihedral angle of 24.26 (9)°. Furthermore, there are intermolecular C—H···O hydrogen bonds between the aromatic H atom (H2) and one sulfonamide O atom (O2i, symmetric code: see table 1) of neighboring molecules that contribute to the three-dimensional packing (Fig. 2).

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

Sulfonamide compounds have gained much importance due to their therapeutic applications. The compound containing cyclohexylamine has been reported to be an activator of dopamine receptors in the CNS (Hacksell et al., 1981). The title compound is a sulfonamide derivative of cyclohexylamine in continuation to our previous work (Arshad et al., 2008; Arshad et al., 2009).
The molecular structure of the title compound (I) is shown in Fig. 1. The mean plane of the benzene ring and that of the four essentially planar C atoms (C8, C9, C11, C12. Maximum deviation, 0.0132 Å) of the chair-form cyclohexyl ring have a dihedral angle of 24.26 (9)°. Furthermore, there are intermolecular C—H···O hydrogen bonds between the aromatic H atom (H2) and one sulfonamide O atom (O2i, symmetric code: see table 1) of neighboring molecules that contribute to the three-dimensional packing (Fig. 2).
