The asymmetric unit of the title compound, C7H7BrN2O, contains two molecules, 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, molecules are linked by N-HO and C-HO hydrogen bonds generating bifurcated R21(5) ring motifs, which in turn lead to  chains.
