In the crystal structure of the title compound, C(15)H(13)BrN(2)O(5)·CH(3)OH, the methanol solvent mol-ecule links symmetry-related mol-ecules through O-H⋯O and N-H⋯O hydrogen bonds. Further inter-molecular O-H⋯O hydrogen bonds link symmetry-related mol-ecules, leading to the formation of a three-dimensional network. Two of the H atoms involved in hydrogen bonding are disordered. The dihedral angle between the rings is 5.64 (14)°.
