Abstract

The mol­ecular structure of the title compound, C18H16N2O3, does not differ in the crystals of the racemic mixture, (I), and the pure enantiomer, (II). In their crystal structures, inversion dimers occur in (I) via N—H⋯O hydrogen bonds and infinite chains in (II) also via N—H⋯O hydrogen bonds.
