Structure description
Imidazo[4,5-b]pyridines are an important class of heterocyclic rings, considered as analogue of purine, widely studied owing to their broad biological activities. For example, they are known for their anticancer activity (Dash et al., 2008) and antibacterial (Capelli et al., 2006), antimitotic (Temple, 1990) and tuberculostatic (Bukowski & Janowiec, 1989) properties. In a previous study, we reported the synthesis of ethyl 2-(6-bromo-2-phenyl-1H-imidazo[4,5-b]-pyridin-1-yl)acetate (Hjouji et al., 2016). The present study is extended to the synthesis of the ethyl 2-(6-bromo-2-phenyl-3H-imidazo[4,5-b]pyridin-3-yl)acetate regioisomer, by the action of ethyl 2-bromoacetate on 6-bromo-2-phenyl-3H-imidazo[4,5-b]pyridine under the same conditions.
The and 2). The bicyclic imidazo[4,5-b]pyridine core of molecule 1 is planar to within 0.012 (1) Å, while that in molecule 2 is planar to within 0.020 (1) Å. In molecule 1, the pendant phenyl ring is inclined to the imidazo[4,5-b]pyridine core by 43.10 (4)° while in molecule 2 the corresponding angle is 49.43 (4)°.
of the title compound, contains two independent molecules (1 and 2), which differ primarily in the conformations of the ester substituents (Figs. 1In the crystal, molecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming sheets parallel to the ab plane (Table 1 and Fig. 3).
Synthesis and crystallization
To a solution of 6-bromo-2-phenyl-1H-imidazo[4,5-b]pyridine (0.30 g, 1.1 mmol), potassium carbonate (0.20 g, 1.42 mmol) and tetra-n-butylammonium bromide 0.035 g (0,11 mmol) in DMF (15 ml) was added ethyl 2-bromoacetate (0.14 ml, 1.30 mmol). The mixture was stirred at room temperature for 12 h. The salt was removed by filtration and the filtrate concentrated under reduced pressure. The residue was separated by on a column of silica gel with ethyl acetate/hexane (1/3) as Crystals were isolated when the solvent was allowed to evaporate (yield 43%)

Experimental. The diffraction data were obtained from 3 sets of 400 frames, each of width 0.5° in ω, colllected at φ = 0.00, 90.00 and 180.00° and 2 sets of 800 frames, each of width 0.45° in φ, collected at ω = –30.00 and 210.00°. The scan time was 20 sec/frame. |
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 > 2sigma(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. H-atoms attached to carbon were placed in calculated positions (C—H = 0.95 - 0.99 Å). All were included as riding contributions with isotropic displacement parameters 1.2 - 1.5 times those of the attached atoms. |
