✦ Synopsis
In the title compound, C~8~H~9~BrN~2~O~2~, the amide bond is in a cis configuation. The N—N—C=O group is planar [torsion angle 0.6 (6)°] and forms a dihedral angle of 46.4 (2)° with the aromatic ring. The crystal packing is stabilized by two strong and one rather weak N—H...O hydrogen bonds.
