| Reactant | Benzene, 2-fluoro-3,4-dimethoxy-1-nitro- | HCID 21999488 | — |
| Catalyst | Adams' catalyst | HCID 345198 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 2-Fluoro-3,4-dimethoxyaniline | HCID 57429548 | 95% |
Reaction Steps
2-Fluoro-3,4-dimethoxy-1-nitrobenzene (52 g, 259 mmol) was hydrogenated on a Par shaker (30 psi) in Ethanol (300 mL) with platinum(IV) oxide (5 g, 22.02 mmol) at r.t. for 30 mins. LCMS indicated completion of the reaction. The catalyst was filtered off and the filtrate was concentrated to afford 2-fluoro-3,4-dimethoxyaniline (42 g, 245 mmol, 95% yield) as a brown oil. LCMS (M+H)+: 172.0.
