الإجراء التجريبي

1.78 g N,N-diethyl-p-nitrosoaniline and 2.65 g 1,3-diphenyl-5-aminopyrazole were refluxed for 2 hrs in acetic acid. The mixture was concentrated to half volume. Water was added to get a precipitate, then filtered. The solid was purified by chromatograph column on silica gel. After removing the solvent, 1.6 g pure 7-diethylamino-1,3-diphenyl-1H-pyrazolo[3,4-b]quinoxaline (DEDPPQ) was obtained as a brown solid.
