Versuchsvorschrift

This compound was prepared by the method of Example 11, utilizing 4-chloro-1-methyl-[1,2,4]triazolo[4,3-a]quinoxaline (the product of Example 3) as starting material in place of 4-chloro-[1,2,4]triazolo[4,3-a]quinoxaline (the product of Example 2) and diethylamine as reagent in place of di-n-propylamine. The crude product obtained was recrystallized from chloroform and then from cyclohexane to afford 7.2 g. (54% yield) of pure 4-diethylamino-1-methyl-[1,2,4]triazolo[4,3-a]quinoxaline, m.p. 123°-5° C.
