Procedure

A clean 3 neck round bottom flask was equipped with magnetic stirring, thermocouple, and nitrogen and placed into an ice bath. 3-Nitroamino-4-nitrofurazan (1.75 grams; 0.01M) is added to 5 mls dry methanol. Dinitroazetidinium (1.47 grams; 0.01 mol) is added slowly over 10 minutes not exceeding 10° C. The resulting mixture is stirred cold for 10 minutes, then the mixture is stirred for an additional hour at room temperature. After transfer to a tarred one neck flask, the solvent is removed in vacuo at 35° C. Recrystallization followed.
