The title compound, C9H10BrNO4S, is an inter­mediate for the formation of benzothia­zines. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules, forming R22(10) ring motifs, which are linked into a two-dimensional polymeric sheet through inter­molecular C—H⋯O hydrogen bonds.

Comment top

The glycine methyl ester is the simplest among the amino acids and the p-bromobenzenesulfonyl chloride is also comercially available. We have synthesized the title compound, (I), from their condensation. It has been prepared as an intermediate for the formation of benzothiazines, which are of our research interest (Arshad et al., 2008; Tahir et al., 2008).

In the molecule of the title compound, (I), (Fig. 1) the bond lengths (Allen et al., 1987) and angles are within normal ranges, and are comparable with the corresponding values in N-(2-nitrophenylsulfonyl)glycine methyl ester, (II), (Bornaghi et al., 2005). Ring A (C4-C9) is, of course, planar, and the Br atom lies slightly out of the ring plane [0.069 (3) Å]. The S1-N1 bond is almost perpendicular to the ring plane, with N1-S1-C4-C5 [-83.4 (3)°] and/or N1/S1/C4/C9 [93.7 (3)°] torsion angles. The (O1/O2/C1-C3) moiety is planar, and it is oriented with respect to ring A at a dihedral angle of 87.74 (3)°.

In the crystal structure, intermolecular N-H···O hydrogen bonds (Table 1) link the molecules to form R22(10) ring motifs (Bernstein et al., 1995), in which they are linked to form a two dimensional polymeric sheet through intermolecular C-H···O hydrogen bonds (Table 1, Fig. 2).

Experimental top

Glycine methyl ester hydrochloride (0.246 g, 1.95 mmol) was dissolved in water (10 ml) in round bottom flask. The pH of the solution was adjusted to 8–9 using sodium carbonate (1 N), and then 4-bromo benzene sulfonyl chloride (0.5 g, 1.95 mmol) was added. The mixture was stirred for 2 h at room temperature. During the reaction, pH was strictly maintained at 8–9 as HCl produced, which lowers the pH. Colorless solid product obtained was washed, dried and recrystalized from methanol for X-ray analysis (m.p. 393-394 K).

Refinement top

H atoms were positioned geometrically, with N-H = 0.86 Å (for NH) and C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C,N), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

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.
