Abstract
The title imidazo [4,5-b] pyridine derivative, C16H14BrN3O2, crystallizes with two independent molecules (1 and 2) in the asymmetric unit. 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)°. The two molecules differ primarily in the conformations of the ester substituents. In the crystal, molecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming sheets parallel to the ab plane.
