Abstract
The title compound, C21H17BrN2O4, a 2-phenoxy-2-phenylacetamide derivative, exhibits a stereogenic center but crystallizes as a racemate as indicated by the centrosymmetric space group. In the molecular structure, the nitro-substituted benzene ring is coplanar [dihedral angle = 12.9 (1)°] with the plane formed by H—N—C(=O)—C=O due to intramolecular N—H⋯O hydrogen-bond interactions.
