Reaction Steps
4-Chloro-1-isopropyl-[1,2,4]-triazolo[4,3-a]quinoxaline (1.0 g., 0.004 mole), the product of Example 6, and 900 mg. (0.012 mole) of diethylamine in N,N-dimethylformamide (15 ml.) were stirred at room temperature for 4 hours. The reaction mixture was poured over ice and the precipitate was separated by means of filtration, washed with water and placed on a column of silica gel (175 ml.) and finally eluted with chloroform. The eluant was evaporated in vacuo to afford 850 mg. (75% yield) of pure 4-diethylamino-1-isopropyl-[1,2,4]triazolo[4,3-a]quinoxaline as a white solid (m.p. 93°-95° C.). Mass spectrum: m/e, 283 (P). The pure product (100 mg.) was then distilled in vacuo (0.1 mm) at 140° to 150° C. to afford the analytical sample (80 mg.), m.p. 94°-96° C.
