Comment top

1,2,4-Oxadiazole derivatives possess biological properties such as intrinsic analgesic (Terashita et al., 2002) and antipicornaviral (Romero, 2001) effects. As part of out studies in this area, we report here the synthesis and crystal structure of the title compound, (I), (Fig. 1).

The dihedral angles between the N1/O1/C9/N2/C8 ring and its adjacent bezene rings are 24.50 (19) and 12.20 (18)° for the C2 and C10 rings, respectively.

An intramolecular, bifurcated N—H···(N,O) hydrogen bond (Table 1) helps to establish the molecular conformation of (I). Some short C—H···O and C—H···N contacts are also present.

Experimental top

2-Chloro-N-(2,6-dimethylphenyl)acetamide (10 mmol) was dissolved in acetone (100 ml) and potassium carbonate (15 mmol) was added. Then, 5-(2-hydroxyphenyl)-3-(4-methylsulfonyl)-phenyl-1,2,4-oxadiazole (10 mmol) was added to the reaction. The resulting mixture was refluxed for 12 h. After cooling and filtering, the crude title compound was obtained and purified by recrystalization from ethyl acetate. Crystals of (I) suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution.

Refinement top

All H atoms were placed geometrically (N—H = 0.86 Å, C—H = 0.93–0.96 Å) and refined as riding with Uiso(H) = 1.2Ueq(carrier) or 1.5Ueq(methyl carrier).

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.
