3-Fluoro-4-nitrophenol → 4-Amino-3-fluorophenol

Participants

Reaction Steps

3-Fluoro-4-nitrophenol (5.0 g, 31.83 mmol) was dissolved in ethyl acetate (50 ml) and tetrahydrofuran (75 ml), and then palladium carbon (2.0 g) was added and the mixture was stirred for 8.5 hours at room temperature under a hydrogen atmosphere. The catalyst was filtered off, the filtrate was washed with ethanol, the solvent was distilled off under reduced pressure and the obtained crystals were washed with addition of hexane:ethanol=1:1. The crystals were filtered out, washed with diethyl ether and dried by aspiration to obtain the title compound (1.62 g, 12.74 mmol, 40.61%) as light yellow crystals.
