A mixture of 7-bromo-2-hydrazinylquinoxaline (200 mg, 0.84 mmol) and AcOH (5 mL) was refluxed overnight. After cooling to r.t., the mixture was treated with water (10 mL); the solid was collected on a filter and dried by vacuum to give 8-bromo-1-methyl-[1,2,4]triazolo[4,3-a]quinoxaline as gray solid (200 mg, yield: 91.0%).
