Ethyl orthoformate → 8-(Benzyloxy)-[1,2,4]triazolo[4,3-a]pyridine

Participants

Reaction Steps

A flask was charged with 3-(benzyloxy)-2-hydrazinylpyridine (10.0 g, 46.5 mmol) and triethoxymethane (77.3 ml, 465 mmol). The mixture was heated at reflux for 1 hour and then stirred overnight at ambient temperature. The solids were filtered and rinsed with EtOH and dried on high vacuum to afford 8-(benzyloxy)-[1,2,4]triazolo[4,3-a]pyridine (8.05 g, 35.7 mmol, 76% yield).
