The reaction of 5,6-diphenyl-3-hydrazino-1,2,4-triazine (1) with bis(methylthio)methylene]malononitrile (2) afforded 5-amino-1-(5,6-diphenyl-1,2,4-triazin-3-yl)-3-(methylthio)-1H-pyrazole-4-carbonitrile (3). Compound 3 reacted with thiourea to give 3,4-diaminopyrazolo[3,4-d]pyrimidine 5, which was treated with benzoyl chloride to give pyrazolo[5,4,3-kl]pyrimido[4,3-d]pyrimidine 6. Treatment of 3 with acetic anhydride produced 3-methylthio-pyrazolo[3,4-d]pyrimidine derivative 7
