Patent ID: 8084619

Claim:
A method of forming a compound comprising the steps of: providing a solution of 5-amino tetrazole and triethyl amine in acetonitrile, wherein 5-amino tetrazole and triethyl amine are provided in roughly equimolar amounts, and acetonitrile is provided in an amount sufficient to solubilize the reactants of this method; adding triphosgene in about 0.3 to 0.4 of the molar amount of the methyl amine, to a solution cooled to 0-10 degrees Celsius; stirring the mixture to form the reaction intermediate, tetrazole isocyanate; adding one equivalent of 5-aminotetrazole/triethylamine; heating to temperatures greater than room temperature, from room temperature to about 80 degrees Celsius; stirring to permit reaction for a sufficient period of time to result in the formation of the compound, wherein said compound has the structural formula of R 3 —R 1 —R 2 wherein R1 is a urea group, R2 is a tetrazolyl group with a C—N bond to the urea group, and R3 is an N-tetrazoylyl, triazolyl, heterocyclic-triazine, heterocyclic amine, aromatic amine, alkenyl, alkynyl, or nitramine group linked to the free nitrogen on the urea group.
