| 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), followed by stirring under a hydrogen atmosphere at room temperature for 24 hr and 20 min. The atmosphere in the reaction vessel was replaced with nitrogen to stop the reaction, and the catalyst was filtered through Celite. The filtrate was removed under reduced pressure to provide the titled compound as a brown solid (4.96 g, 99%).
