Reaction Steps

[6-(1-Methyl-1H-pyrazol-4-yl)-pyridazin-3-yl]-hydrazine (1.0 g, 5.3 mmol) and 1,1′-thiocarbonyldiimidazole (1.08 g, 6.1 mmol) were combined in DMF (10 mL) and heated at 50° C. for 2 h. After such time the mixture was allowed to cool to room temperature. Hexane (10 mL) was added followed by THF (4 mL), stirred for 10 mins then filtered and washed with THF (2 mL then 4 mL). Solid dried in vacuo to return 738 mg of 6-(1-methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine-3-thiol as a yellow solid (60% yield).
