Reaktionsschritte

5.000 grams, 59.4 mmoles of 4-amino-1,2,4-triazole was dissolved in 200 ml of fresh acetonitrile and stirred vigorously. 29.800 grams of 2-bromoethanol was added slowly to the solution by pipet. After the addition was complete, the reaction mixture was heated for 20 hours at 80° C., until thin layer chromatography revealed that all of the 4-amino-1,2,4-triazole had been consumed. The reaction mixture was then allowed to cool to room temperature and then was rotary evaporated down to leave a viscous oil. Hot isopropyl alcohol was added to the oil dissolving it. Storage of the resultant solution in a refrigerator resulting in a large crop of a viscous oil of 1-ethanol-4-amino-1,2,4-triazolium bromide, 9.9332 g, 47.5 mmoles. Melting point 0-5° C.; DSC onset 180° C.
