Participants

Reaction Steps

The synthesis method of Example 1-(3) was applied. 3-Amino-1H-1,2,4-triazole (5.00 g), dimethylformamide (30 ml) and methyl isocyanate (4.0 ml) were used as reagents. The mixture was stirred at room temperature i:or 18 hours and 6.83 g of the resulting solid (yield 81%) was collected by filtration. The obtained solid was recrystallized from ethyl acetate to give colorless transparent crystals.
