Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol, 1,1-diethoxy-, 1-acetate | HCID 84166 | — |
| Reactant | 5-Fluoro-2-hydrazinylpyridine | HCID 19916786 | — |
| Solvent | Cyclohexane | HCID 8078 | — |
| Product | 6-Fluoro-[1,2,4]triazolo[4,3-a]pyridine | HCID 55267245 | 70% |
Reaction Steps
(5-Fluoro-pyridin-2-yl)-hydrazine (500 mg, 3.93 mmol) in diethoxymethyl acetate (5 mL) was stirred at RT for 2 h. The resulting precipitate was diluted with cyclohexane (5 mL) and filtered to give the title compound (379 mg, 70%). 1H NMR (400 MHz, CDCl3): 7.25 (1H, m), 7.84 (1H, m), 8.09 (1H, t), 8.84 (1H, s).
