Synthesis of Spiro[indolo[۲'۱-b]quinazoline-۶'۴'-pyrazolo[۳'۴-d]pyrimidin]-۶'-yl)cyanamides

In this research, trichloroacetic acid (TCAA) promoted the synthesis of spiro[indolo[۲'۱-b]quinazoline-۶'۴'-pyrazolo[۳'۴-d]pyrimidin]-۶'-yl)cyanamides by the reaction of tryptanthrins, cyanoguanidine, and ۳-methyl-pyrazol-۵(۴H)-ones in CH۳CN.
