3-Benzyl-6-bromo-1H-imidazo[4,5-b]pyridin-2(3H)-one

The fused imidazole and pyridine rings in the title compound, C₁₃H₁₀BrN₃O, are linked to a benzyl group. The fused ring system is essentially planar, the largest deviation from the mean plane being 0.006 (2) Å. The phenyl ring is not coplanar with the fused ring system, as indicated by the dihedral angle of 67.04 (12)°. In the crystal, mol­ecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers.
