(Received 26 May 2010; accepted 3 June 2010; online 5 June 2010)

In the title compound, C8H9ClN2O3S, the benzene ring makes a dihedral angle of 4.1 (9)° with the amido –NHCO– plane including the major occupancy component of the carbonyl O atom [19 (4)° for the minor component]. An intra­molecular C—H⋯O inter­action occurs. The O atom of the carbonyl group is disordered over two positions with site-occupancy factors of 0.67 (11) and 0.33 (11). Inter­molecular N—H⋯O hydrogen bonds help to stabilize the crystal structure.

Comment top

Sulfonamide is the basis of several groups of drugs. The original antibacterial sulfonamides (sometimes called simply sulfa drugs) are synthetic antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial activity, e.g., the anticonvulsant sultiame. The sulfonylureas and thiazide diuretics are newer drug groups based on the antibacterial sulfonamides. Sulfanilamide is a sulfonamide antibacterial.

Carbonic anhydrases (CAs, EC 4.2.1.1) are widespread metalloenzymes in bacteria, archaea, and eukaryotes, catalyzing a critically important physiologic reaction, hydration of carbon dioxide to bicarbonate and protons (Ohradanova et al., 2007; Supuran, 2008). These enzymes are inhibited by several classes of compounds, such as sulfonamides, sulfamates and sulfamides some of which have pharmacologic applications for the treatment of glaucoma obesity cancer epilepsy and other neurological disorders or as diuretics (Supuran, 2008; Köhler et al., 2007; Türkmen et al., 2005; Thiry et al., 2008). In view of these importance, we have undertaken the crystal structure determination of the compound 2-chloro-N-(4-sulfamoylphenyl)acetamide and the results are presented here.

In the molecular structure of the title compound, (I), (Fig. 1), the S=O distances are 1.432 (2) and 1.433 (2) Å, and the angle of O=S=O is 118.38 (14)°. All the bond lengths and the bond angles are within the normal range (Allen et al., 1987). The planes of the benzene ring and the O=S=O group make a dihedral angle of 126.81 (11)°. The C4—N2—C7—C8, N2—C7—C8—Cl1 and C4—N2—C7—O3B torsion angles in the 2-chloroacetamide part of the molecule are -173.3 (3), -157.8 (2) and -4.8 (14)°, respectively.

In the crystal structure, symmetry-related molecules are interconected by intermolecular N—H···O hydrogen bonds (Table 1) to form a three-dimensional network (Fig.2).

Experimental top

Sulfanilamide (1.00 g, 0.0058 mol) and N-ethylmaleimide (NEM) (0.80 g, 0.007 mol) were stirred in THF (200 ml) until most of the starting material had dissolved. 2-Chloroethanoylchloride (0.784 g, 0.007 mol) in THF was slowly added to the reaction mixture. The reaction was stirred at 258 K for 4 h under anhydrous conditions. After warming to room temperature the white precipitate of NEM/HCl salt filtered off. The THF was removed in vacuo and the resulting white solid dissolved in ethyl acetate. The organic extract was washed with 3M hydrochloric acid (20 ml) then with saturated sodium bicarbonate solution (20 ml) and finally with brine. Drying over magnesium sulfate and evaporation yielded a white solid which was recrystallized from water to give the title compound (yield: 70%, m.p: 492–495 K).

Refinement top

The NH2 H atoms were located in a difference Fourier map, and were refined with distance restraints of N–H = 0.86 (2) Å; their temperature factors were freely refined. The rest H atoms were positioned geometrically and allowed to ride on their respective parent atoms, with C—H = 0.93 (Ar—H) or 0.97 (CH2) Å and N—H = 0.86 (NH) \%A, and with Ueq = 1.2Ueq(C, N). The O atom of the carbonyl group is disorder over two sets of sites [occupancy ratio = 0.67 (11):0.33 (11)].

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 e.s.d.'s 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.
