The dihydroquinoxaline moiety is planar and the majority of the ester substituent is nearly perpendicular to its mean plane. In the crystal, the molecules form oblique stacks along the b-axis direction through slipped π-π-stacking interactions between adjacent dihydroquinoxaline units. The stacks are connected by additional C—H⋯O hydrogen bonds and C—H⋯π(ring) interactions to form an open three-dimensional network.
