3-[2-(5H-Indolo[2,3-b]quinoxalin-5-yl)ethyl]-1,3-oxazolidin-2-one

Abstract

The title compound, C19H16N4O2, has an almost planar fused N-heterocyclic system (r.m.s. deviation = 0.031 Å) and an almost planar five-membered 1,3-oxazolidine ring (r.m.s. deviation = 0.015 Å) at the ends of an ethylene chain [N-C-C-N torsion angle = -65.6 (2)°]. The ring systems are inclined at 38.1 (1)° to one another.
