Reaction Steps

5-Nitro-2-(1H-tetrazol-1-yl)pyridine (1020 mg, 5.31 mmol) was suspended in acetic acid (10 ml). Zinc (3472 mg, 53.1 mmol) was added slowly (exothermic reaction). The mixture was stirred at 50° C. for 1 hour, cooled, diluted with EtOAc. The mixture was filtered, rinsed with ethyl acetate. The filtrate was concentrated to dryness to give crude 6-(1H-tetrazol-1-yl)pyridin-3-amine: LC/MS: [(M+1-28)]+=135.1.9.
