Reaktionsschritte

To 500 mg of 10% palladium on carbon in a Parr bottle containing 50 ml of anhydrous ethanol was added a solution of 10 g (64 mmol) 5-fluoro-2-nitrophenol in 150 ml ethanol. The flask was evacuated, charged with hydrogen and shaken on a Parr apparatus for 1 hour. The catalyst was removed by filtration through. Celite® and the filtrate was evaporated to dryness in vacuo to give 7.54 g (93% yield) of a dark solid.
