In the title compound, C14H20N2O3S, the cyclohexyl ring adopts a chair conformation: the four coplanar C atoms of this ring make a dihedral angle of 64.8 (2)° with the benzene ring. In the molecule, an intramolecular C—H⋯O contact generates an S(6) ring motif. In the molecules are linked via intermolecular N—H⋯O hydrogen bonds into two-dimensional layers propagating in (100).

To 0.5 g ( 1.96 mmol ) N-acetyl p-amino sulfonyl chloride in 10 ml of distilled water was added 0.23 ml of cyclohexylamine (1.96 mmol) and stirring continued at room temperature, while maintaining the pH of the reaction mixture at 8 using 3% sodium carbonate. The progress of the reaction was continuously monitored by TLC. After consumption of all the reactants the mixture was filtered, dried and recrystalized from ethyl acetate to yield colourless needles of (I).
All H atoms were positioned geometrically and were treated as riding on their parent atoms, with N—H = 0.86 Å and C—H = 0.93-0.98 Å and Uiso(H) = 1.2 or 1.5Ueq(N, C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

The title compound (I), (Fig.1), was prepared and characterized as part of our ongoing studies of sulfonamide derivatives (Mariam et al., 2009a,b; Sharif et al., 2010).
The bond lengths (Allen et al., 1987) and angles are within the normal ranges and are comparable to those in similar structures (Sharif et al., 2010; Mariam et al., 2009a,b; Asiri et al., 2009; Khan et al., 2009; Arshad et al., 2008; Gowda et al., 2007a,b,c; Haider et al., 2010).
The C1–C6 cyclohexyl ring of (I) adopts a classic chair conformation [puckering parameters (Cremer & Pople, 1975) QT = 0.559 (6) Å, θ = 180.0 (6) ° and ϕ = 212 (16) °]. Atoms C1 and C4 deviate by -0.667 (6)Å and 0.639 (4) Å, respectively, from the plane through the other four atoms (C2,C3, C5 and C6) of the cyclohexane ring. The dihedral angle between the benzene ring (C7–C12) and the C2/C3/C5/C6 least-squares plane of the cyclohexane ring is 64.76 (20)° (Nardelli, 1983).
In the molecule of (I), intramolecular C—H···O hydrogen contacts generate S(5) and S(6) ring motifs (Bernstein et al., 1995) (Table 1). In the crystal structure of (I), molecules are linked via intermolecular N—H···O hydrogen bonds into two-dimensional layers extended along the b axis (Table 1 and Fig. 2).
