چکیده
In the title mol-ecule, C(15)H(13)BrN(2)O(2), an intra-molecular O-H⋯N hydrogen bond influences the mol-ecular conformation; the two benzene rings form a dihedral angle of 13.6 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis and weak inter-molecular C-H⋯O hydrogen bonds further link these chains into layers parallel to the ac plane.
