실험 절차

5-Bromo-2-(1H-1,2,4-triazol-3-yl)pyridine. A solution of (E) -5-bromo-N-((dimethylamino)methylene)picolinamide (0.604 mg, 2.36 mmol) and hydrazine (2.12 g, 66.1 mmol) was stirred at 25° C. for 3 h. The reaction was concentrated and diluted with water. The resulting precipitate was collected by filtration and dried under vacuum to give the title compound (0.442 g, 83% yield). MS (ESI) m/z 226.1 [M+1]+.
