|---|---|---|---|
| Reactant | Carbamic acid, N-(3-bromo-5-chloro-2-fluorophenyl)-, 1,1-dimethylethyl ester | HCID 51034463 | — |
| Solvent | Trifluoroacetic acid methylene chloride | HCID 21863450 | — |
| Product | 3-Bromo-5-chloro-2-fluorobenzenamine | HCID 51034225 | 117.9% |
Reaction Steps
A solution of tert-butyl 3-bromo-5-chloro-2-fluorophenylcarbamate (900 mg, 2.78 mmol) in DCM/TFA (1:1, 20 mL) was stirred at rt for 1 h. The reaction mixture was concentrated, then the residue was taken up in ethyl acetate and washed with aqueous sodium bicarbonate and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated to provide the crude title compound (736 mg). MS m/z 223.9 (M+1).
