(S)-Ethyl 2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propanoate

Abstract

In the molecule of the title compound, C19H17ClN2O4, the quinoxaline ring system is planar [maximum deviation = 0.013 (3) Å] and oriented at a dihedral angle of 80.18 (3)° with respect to the benzene ring. In the crystal structure, intermolecular C—H...N interactions link molecules into chains. π–π contacts between the quinoxaline systems [centroid–centroid distance = 3.654 (1) Å] may further stabilize the structure.
