In the title compound, C13H19BrNO4P, the crystal structure is stabilized by inter-molecular N- H⋯O hydrogen bonds between the phosphoryl O atom and the amide N atom which link the mol-ecules into centrosymmetric dimers. These dimers are further packed into stacks along the c axis by inter-molecular C- H⋯O and C- H⋯π inter-actions
