In the title compound, C(28)H(24)N(2)O(4), the dihedral angle between the two rings of the biphenyl unit is 75.34 (9)°. The outer aromatic rings form dihedral angles of 66.96 (1) and 85.69 (8)° with the rings to which they are attached . The mol-ecular structure is stabilized by intra-molecular C-H⋯O and N-H⋯O hydrogen bonds. In the crystal structure, inter-molecular N-H⋯O inter-actions are observed.
