In the title compound, C15H12ClNO3, the central C—C(O)—N—C amide unit makes dihedral angles of 6.60 (2) and 3.42 (2)°, respectively, with the 4-chlorobenzene and anilino rings. The dihedral angle between the two benzene rings is 3.32 (3)°. Intramolecular N—H⋯O and C—H⋯O hydrogen bonds form S(6) rings and contribute to the planarity of this portion of the molecule. In the crystal, intermolecular C—H⋯O hydrogen bonds are observed, which link the molecules into [010] C(7) chains.

A solution of methyl anthranilate (390 µl, 3 mmol) in dichloromethane (15 ml) was treated dropwise with 4-chlorobenzoyl chloride (383 µl, 3 mmol) in the presence of triethanolamine (5 ml) as a catalyst. The resulting mixture was stirred for 1 h. On completion of reaction, precipitates formed, were filtered, dried and crystallized from methanol to yield colorless blocks of the title compound.
All H-atoms were refined using riding model for hydrogen bonds with d(C—H) = 0.93Å (Uiso=1.2Ueq of the parent atom) for aromatic carbon atoms, d(N—H) = 0.86Å (Uiso=1.2Ueq of the parent atom) for imine nitrogen atom and d(C—H) = 0.96Å (Uiso=1.5Ueq of the parent atom) for methyl carbon atom.
Benzamide derivatives are frequently used in the synthesis of new and effective anti-convulsant agents (Clark et al., 1988; Leander et al., 1988; Diouf et al., 1997). In continuation of our ongoing structural studies of benzamide derivatives (Khan et al., 2010), herein the
of title compound is described.In the title compound, Fig. 1, the C1—N1—C9(O1)—C10 amide unit is planar, r.m.s. deviation 0.0102 Å, and subtends dihedral angles of 3.42 (2)° and 6.60 (2)° respectively to the C1···C6 and C10···C15 rings. The two aromatic rings are inclined at 3.32 (3)°. Bond distances within the molecule are normal (Allen et al. 1987) and similar to those observed in comparable structures (Gowda et al. 2008; Zhou & Zheng 2007).
The intramolecular C2—H2···O1 and N1—H1···O2 hydrogen bonds produce S(6) rings (Bernstein et al., 1995) (Fig. 1). The C3—H3 group in the molecule at acts as a hydrogen-bond donor to atom O2i (symmetry code: -x+1/2, y+1/2, z) forming a C(7) chain running parallel to the [010] direction (Fig. 2).

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

Benzamide derivatives are frequently used in the synthesis of new and effective anti-convulsant agents (Clark et al., 1988; Leander et al., 1988; Diouf et al., 1997). In continuation of our ongoing structural studies of benzamide derivatives (Khan et al., 2010), herein the crystal structure of title compound is described.
In the title compound, Fig. 1, the C1—N1—C9(O1)—C10 amide unit is planar, r.m.s. deviation 0.0102 Å, and subtends dihedral angles of 3.42 (2)° and 6.60 (2)° respectively to the C1···C6 and C10···C15 rings. The two aromatic rings are inclined at 3.32 (3)°. Bond distances within the molecule are normal (Allen et al. 1987) and similar to those observed in comparable structures (Gowda et al. 2008; Zhou & Zheng 2007).
The intramolecular C2—H2···O1 and N1—H1···O2 hydrogen bonds produce S(6) rings (Bernstein et al., 1995) (Fig. 1). The C3—H3 group in the molecule at acts as a hydrogen-bond donor to atom O2i (symmetry code: -x+1/2, y+1/2, z) forming a C(7) chain running parallel to the [010] direction (Fig. 2).
