7-Azidofurazano[3,4-b]tetrazolopyrazine (FSZPA) was synthesized via methoxylation, nitration hydrazinolysis and azidation, using 2,6- dichloropyrazine as a starting material. The structures of 7-azidofurazano[3,4- b]tetrazolopyrazine and intermediates were identified by FTIR, NMR and elemental analysis. 15N and 13C NMR spectra showed three isomer forms resulting from the reversible opening and closing between asido and tetrazole depending on polarity of the solvents.

Paragraph 0031-0037, (2022/02/24)
The present invention belongs to the field of synthesis technology of compounds, specifically disclosed a method of synthesis of dibromo compounds. The method of the present invention takes a dichloro compound as a raw material, first reacts with sodium methanol to form a dimethoxy compound, and then reacts with a bromination reagent to give a dibromo compound. The method of the present invention is not only mild reaction conditions, simple operation, and the reaction product is single, through simple post-treatment, and then the target product can be obtained at a high yield, it is expected to be developed as an industrial production method.
