In the title compound, C15H15NO4S, the dihedral angle between the phenyl and benzene rings is 46.0 (3)° and a weak intramolecular N—H⋯O interaction is present. The is stabilized by intermolecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds.

Phenyl glycine (1.0 g, 6.6 mmol) was dissolved in 20 ml distilled in a round bottom flask (100 ml). 1M Na2CO3 solution was used to maintain pH at 8–9. Para-toluene sulfonyl chloride (1.26 g, 6.6 mmol) was added to the solution, and stirred at room temperature until the para-toluene sulfonylchloride was consumed. On completion of the reaction, while vigorous stirring pH was adjusted 1–2, using 1 M HCl. The precipitate formed in this way was filtered off, washed with distilled water, dried and recrystalized in methanol and ethyl acetate (50:50 v/v) to yield light brown prisms of (I).
The NH H atom was localized from the difference-Fourier map and its coordinates were refined freely. The isotropic temperature parameters of the H atom were calculated as 1.2Ueq of the parent atom. H atoms were located geometrically and treated as riding with C—H = 0.98 Å (methine), C—H = 0.96 Å (methyl), C—H = 0.93 Å (aromatic) and O—H = 0.82 Å (hydroxyl) with Uiso(H) = 1.2 or 1.5Ueq(C, O).
(R)-alpha-Amino-benzeneacetic is a side chain component of Ampicillin, Cephalexin and Cephaclor. Cephalexin has D-phenylglycyl group as a substituent at the 7-amino position and an unsubstituted methyl group at the 3-position. This is in connection with our previous study on synthesis of sulfonamide derivatives with phenyl glycine (Arshad et al., 2009).
In the title molecule (I), (Fig. 1), bond lengths (Allen et al., 1987) and bond angles are in the range of expected values. The planes of the phenyl and benzene rings (C1–C6) and (C9–C14) make a dihedral angle of 46.0 (3) ° with each other.
In the structure, the adjacent molecules are connected by intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds (Table 1). In Fig. 2, the packing and hydrogen bonding of (I) are shown viewed down a axis.

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. |

(R)-alpha-Amino-benzeneacetic is a side chain component of Ampicillin, Cephalexin and Cephaclor. Cephalexin has D-phenylglycyl group as a substituent at the 7-amino position and an unsubstituted methyl group at the 3-position. This is in connection with our previous study on synthesis of sulfonamide derivatives with phenyl glycine (Arshad et al., 2009).
In the title molecule (I), (Fig. 1), bond lengths (Allen et al., 1987) and bond angles are in the range of expected values. The planes of the phenyl and benzene rings (C1–C6) and (C9–C14) make a dihedral angle of 46.0 (3) ° with each other.
In the structure, the adjacent molecules are connected by intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds (Table 1). In Fig. 2, the packing and hydrogen bonding of (I) are shown viewed down a axis.
