| Reactant | 4-Bromo-3-nitroanisole | HCID 79288 | — |
| Catalyst | Nickel | HCID 935 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 2-Bromo-5-methoxyaniline | HCID 793016 | 86.3% |
Reaction Steps
A mixture of 1-bromo-4-methoxy-2-nitro-benzene (10 g, 43 mmol) and Raney Ni (5 g) in ethanol (100 mL) was stirred under H2 (1 atm) for 4 h at room temperature. Raney Ni was filtered off and the filtrate was concentrated under reduced pressure. The resulting solid was purified by column chromatography to give 2-bromo-5-methoxy-phenylamine (7.5 g, 86%).
