Abstract: Embodiments of this disclosure describe a method for synthesizing potassium 5,7-dinitro-[2,1,3]-benzoxadiazol-4-olate-3-oxide (benzofuroxan derivative). In the method, a nucleophilic displacement reaction was conducted between sodium azide and 3-chloro-2,4,6-trinitrophenol. The reaction was performed at a controlled temperature using a suitable reaction medium consisting of water and methanol. After the completion of the reaction, the mixture was allowed to cool down to room temperature. On further cooling, a solid precipitated out of the reaction mixture. The solid is filtered and air-dried to give the sodium analogue of the benzofuroxa derivative. The analogue is a crucial precursor of the benzofuroxan derivative. The sodium cation is subsequently replaced with potassium by carrying the precursor through a series of operations. First, it was treated with a methanolic hydrochloric acid. The treatment removed the sodium cation and introduced a proton in its place. Sodium chloride thus was filtration off.

Abstract: Embodiments of this disclosure describe a novel method for synthesizing a tetrazole derivative. The distinguishing feature lies in using aminoguanidine nitrate or aminoguanidine bicarbonate as the starting material, replacing the highly sensitive tetrazine. In a single operational step, the aqueous solution of the starting material is treated with sodium nitrite. The treatment resulted in the precipitation a solid product. Without isolating the intermediate, the solid is subjected undergoes Sandmeyer reaction conditions in-situ, involving nitric acid and sodium nitrite. The resulting solid is filtered, washed with cold water and isopropyl alcohol, and dried to obtain the tetrazole derivative. By eliminating the safety risks associated with the Hamiltonian precursor and streamlining the process, the invention offers a safer, more efficient, and commercially viable method for synthesizing the tetrazole derivative.
