title: (S)-Ethyl 2-[4-(6-chloro-quinoxalin-2-yl-oxy)phen-oxy]propanoate.
abstract: In the mol-ecule of the title compound, C(19)H(17)ClN(2)O(4), 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, inter-molecular C-H⋯N inter-actions link mol-ecules into chains. π-π contacts between the quinoxaline systems [centroid-centroid distance = 3.654 (1) Å] may further stabilize the structure.
