The asymmetric unit of the title compound, C(7)H(7)BrN(2)O, contains two mol-ecules, in one of which the methyl H atoms are disorderd over two orientations in a 0.57 (3):0.43 (3) ratio. The dihedral angles between the pyridine rings and the acetamide groups are 7.27 (11) and 8.46 (11)°. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds generating bifurcated R(2) (1)(5) ring motifs, which in turn lead to [110] chains.
标题化合物C₇H₇BrN₂O的不对称单元包含两个分子，其中一个分子中的甲基氢原子在两个取向之间无序排列，比例为0.57 (3):0.43 (3)。吡啶环与乙酰胺基团之间的二面角分别为7.27 (11)°和8.46 (11)°。在晶体中，分子通过N-H⋯O和C-H⋯O氢键相连，形成分叉的R₂²(₁)(₅)环 motif，进而形成[110]链。
