1-(6-Nitro-pyridin-3-yl)-azetidin-3-ol → 1-(6-Aminopyridin-3-yl)azetidin-3-ol

Participants

Reaction Steps

A 100-mL single-neck round-bottomed flask was purged with nitrogen and charged with 147a (1.0 g, 5.1 mmol), 10% palladium on carbon (10% wet, 100 mg), and ethanol (40 mL). The mixture was evacuated, charged with hydrogen gas, and stirred at room temperature for 5 h. The hydrogen was then evacuated and nitrogen was charged into the flask. The catalyst was removed by filtration through a pad of CELITE® and the filtrate was concentrated under reduced pressure to afford 147b as a yellow solid (792 mg, 85%). MS-ESI: [M+H]+ 166.1.
