Dimethyl 2-aminobiphenyl-4,4′-dicarboxylate

The title compound, C16H15NO4, exhibits two near-planar aromatic ester groups with a maximum aryl–ester torsion angle of 1.9 (2)°. The dihedral angle between the benzene rings is 44.7 (1)°. In the crystal, N—H⋯O hydrogen bonding is observed along with C—H⋯O contacts, forming chanins along [101]. No π–π interactions were noted between the benzene rings.
