Tetrahydrofuran → 4-Amino-3-fluorophenol

Participants

Reaction Steps

To a solution of 3-fluoro-4-nitrophenol (20 g) in ethanol (200 ml)-tetrahydrofuran (125 ml) was added 10% palladium carbon (6.0 g), followed by stirring under a hydrogen atmosphere at room temperature for 4.5 hrs. The mixture was filtered to remove the catalyst, which was washed with ethanol. The filtrate was concentrated under a reduced pressure to provide the titled compound (16.1 g, 100%) as a pale yellow solid.
