Abstract
In the title compound, C16H14BrN3O2, the fused-ring system is essentially planar, with the largest deviation from the mean plane being 0.0216 (15) Å for the substituted N atom of the five-membered ring, the plane of which makes dihedral angles of 28.50 (7) and 77.48 (7)° with the terminal phenyl ring and the ethoxycarbonylmethyl group mean planes, respectively. In the crystal, C—H...N hydrogen bonds link the molecules into inversion dimers. These combine with weak C—H...N contacts to stack the molecules into columns along theb-axis direction.

Summary
Imidazo[4,5-b]pyridine derivatives are often defined as precursors in the synthesis of a variety of therapeutic agents. It makes dihedral angles of 28.50 (7) and 77.48 (7), respectively, with the terminal phenyl ring (C7– C12) and the mean plane of the ethoxycarbonylmethyl group (C13, C14, O1, O2, C15 and C16). C9—H9Á Á ÁN1 (Àx + 1, Ày, Àz + 1) hydrogen bonds (Table 1) link the molecules into inversion dimers. These combine with weak C13—H13AÁ Á ÁN2(x, y + 1, z) contacts to stack the molecules into columns along the b-axis direction (Fig. 2)
