Two isomers were isolated during the reaction between 3-methyl-quinoxalin-2-one and bis-(2-chloro-ethyl)amine hydro-chloride. The crystal structure of one isomer has already been reported [Caleb, Bouhfid, Essassi & El Ammari (2009). Acta Cryst. E65, o2024-o2025], while that of the second isomer is the subject of this work. The title compound, C(14)H(15)N(3)O(3), has a new structure containing oxazolidine and quinoxaline rings linked by an eth-oxy group. The main difference between the two isomers is the position of the oxazolidine group with respect to the quinoxaline system. The dihedral angle between the fused planar rings and the oxazolidin-2-one ring is 41.63 (8)° in the title mol-ecule.
在3-甲基喹喔啉-2-酮与双（2-氯乙基）胺盐酸盐的反应过程中分离出了两种异构体。其中一种异构体的晶体结构已有报道[Caleb, Bouhfid, Essassi & El Ammari (2009). Acta Cryst. E65, o2024 - o2025]，而第二种异构体的晶体结构则是本研究的主题。标题化合物C(14)H(15)N(3)O(3)具有一种新结构，包含通过乙氧基相连的恶唑烷环和喹喔啉环。这两种异构体之间的主要差异在于恶唑烷基团相对于喹喔啉体系的位置。在标题分子中，稠合平面环与恶唑烷-2-酮环之间的二面角为41.63 (8)°。
