Procedure

5-Aminotetrazole hydrate (10.3 g, 0.1 mole) was slurried into 150 ml of water containing 10 ml of 37 percent HCl. A solution of potassium cyanate (10 g, 0.12 mole) was added at ambient temperature over the course of one hour. When a slight exotherm began, the solution was cooled to 10° C. The mixture was stirred two hours, filtered and recrystallized from ethanol.
