The asymmetric unit of the title compound, C₁₆H₁₆ClNO₂, contains two crystallographically independent molecules, which differ mainly in the orientation of the benzyl group with respect to the rest of the molecule. In the crystal packing, centrosymmetrically related molecules are linked into dimers via intermolecular C—H⋯O hydrogen-bond interactions.

Comment top

As part of our continuing project on the study of the interactions occurring between small molecules and proteins (Li et al.; 2008), we report here the synthesis and crystal structure of the title compound.

The asymmetric unit of the title compound (Fig. 1) contains two crystallographically independent molecules which differ mainly in the orientation of the benzyl groups (C10—C15 and C26—C32) bound to the amidic N atoms with respect of the mean plane through the rest of the molecule (dihedral angles of 87.03 (8) and 68.74 (6)° respectively). The O1—C8—C9—O2 and O3—C24—C25—O4 torsion angles are -176.5 (3) and -179.0 (3)°, respectively. These values can be compared with that of 10.5 (3)° found in the similar dichloro compound (Li et al.; 2008). In the crystal structure, centrosymmetrically related molecules are linked into dimers by intermolecular C—H···O hydrogen bonds (Table 1), forming fourteen-membered rings of graph set motif R²₂(14) (Bernstein et al., 1995).

Experimental top

A solution of 2-chloro-5-methylphenol (1.0 mmol), N-benzyl-2-chloroacetamide (1.1 mmol), K₂CO₃ (1.1 mmol) and CH₃CN (20 ml) was refluxed for 3 h. After completion of the reaction (by TLC monitoring), the solution was cooled and the solvent was evaporated under reduced pressure. The residue was poured into water and adjusted to pH 6–7 with dilute hydrochloric acid (10%) and extracted with ethyl acetate, washed with brine and dried over anhydrous MgSO₄. The mixture was then filtered and the filtrate obtained was concentrated under reduced pressure to obtain the corresponding crude product. The product was purified by column chromatography on silica gel using ethyl acetate as eluent (yield 86%). Crystals suitable for X-ray diffraction were obtained by slow evaparation of an ethyl acetate/hexane (1:1 v/v) solution at room temperature for 10 days.

Special details top

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.
