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
To a solution of 1-(benzyloxy)-2,5-difluoro-4-nitrobenzene (9.21 g) in methanol (300 ml) was added 10% palladium on carbon (921 mg), and the mixture was stirred at room temperature for 24 hours and 20 minutes under a hydrogen atmosphere. After terminating the reaction by substituting the atmosphere in the flask with nitrogen, the catalyst was filtered using Celite. The filtrate was distilled off under reduced pressure to give the title compound (4.96 g, 99%) as a brown solid.
