1-(Benzyloxy)-2,5-difluoro-4-nitrobenzene → 4-Amino-2,5-difluorophenol
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1-(Benzyloxy)-2,5-difluoro-4-nitrobenzene | HCID 57470868 | — |
| Catalyst | Palladium | HCID 23938 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | 4-Amino-2,5-difluorophenol | HCID 2778762 | 99% |
Reaction Steps
10% palladium on carbon (921 mg) was added to a solution of 1-(benzyloxy)-2,5-difluoro-4-nitrobenzen (9.21 g) in methanol (300 ml), followed by stirring at room temperature under hydrogen atmosphere for 24 hours and 20 minutes. The air of the flask was replaced with nitrogen to stop the reaction, and the catalyst was removed by filtration using celite. The filtrate was distilled off under reduced pressure to give the title compound (4.96 g, 99%) as a pale brown solid.
