N-(4-Methoxy-2-nitrophenyl)-2-(3-methyl-2-oxo-1,2-dihydroquinoxalin-1-yl)acetamide.

ABSTRACT: The quinoxaline unit in the title mol-ecule, C₁₈H₁₆N₄O₅, is slightly puckered [dihedral angle between the rings = 2.07 (12)°] while the whole mol-ecule adopts an L-shaped conformation. Intra-molecular hydrogen bonding determines the orientation of the substituted phenyl ring and the amide nitro-gen atom is almost planar. The packing in the crystal is governed by C-H⋯O hydrogen bonds and slipped π-stacking inter-actions.
