title: tert-Butyl N-(5-bromo-1H-imidazo[4,5-b]pyridin-2-ylmeth-yl)carbamate.
abstract: In the mol-ecule of the title compound, C(12)H(15)BrN(4)O(2), the imidazole and pyridine rings are strictly coplanar [maximum deviation 0.006 (3) Å]. In the crystal structure, mol-ecules are linked into chains running parallel to the a axis by inter-molecular N-H⋯O hydrogen bonds. Centrosymmetrically related chains are further connected by N-H⋯N hydrogen-bonding inter-actions to form a two-dimensional layer structure parallel to the ab plane.
