Reaction Steps
5-Aminotetrazole (5.5 g, 0.065 mole) was dissolved in 75 ml of DMF. On the addition of methylisocyanate (5 g) the temperature began to slowly rise to 40° C. with the formation of a white solid. The solution was heated for 90 minutes at 100° C. and on cooling, poured into cold water. The resulting white solid was filtered, water washed and dried to give 8.3 g of product which softened at 264°-267° C. but was not melted completely at 305° C.
