Ethyl 2-(3-oxo-1,2,3,4-tetrahydroquinoxalin-2-yl)acetate

Abstract

In the title compound, C12H14N2O3, the conformation of the ester substituent is partially determined by an intramolecular N—H...O hydrogen bond. The crystal packing consists of layers parallel to (\overline{1}12) held together by N—H...O and C—H...O hydrogen bonds. The CH/NH portion of the heterocyclic ring is disordered over two sites in a 0.930 (5):0.070 (5) ratio with the disorder also extending to the O atom involved in the intramolecular N—H...O hydrogen bond.
