実験手順
3.08 g. of 4-hydrazino-1-methylpyrazolo[3,4-d]pyrimidine and 3.56 g. of 1,1-thiocarbonyldiimidazole in 100 ml. of dimethylformamide are stirred at 5° over a period of 16 hours. The 7-methyl-3-mercapto-7H-pyrazolo[4,3-e][1,2,4]-triazolo[4,3-c]pyrimidine which has been formed is filtered under suction, washed with water and recrystallized from a little dimethylformamide as yellowish crystals, m.p. 252°-254°.
