The following two examples were prepared in an analogous manner from the appropriate 2(3)-chloro-3(2)-hydrazinoquinoxaline. The 2-Chloro-3-hydrazino-6-trifluoromethylquinoxaline and 3-chloro-2-hydrazino-6-trifluoromethylquinoxaline isomers were prepared from 2,3-dichloro-6-trifluoromethylquinoxaline by treatment with hydrazine hydrate in dichloromethane, and separated by column chromatography (silica gel) with toluenemethyl acetate (3:1).
