| Reactant | 3-Bromophenyl isocyanate | HCID 141001 | — |
| Reactant | 2-Amino-5-Nitrophenol | HCID 4984721 | — |
| Product | N-(2-hydroxy-4-nitrophenyl)-N'-(3-bromophenyl)urea | HCID 21184715 | 87% |
Reaction Steps
N-(2-Hydroxy-4-nitrophenyl)-N′-(3-bromophenyl)urea was prepared from 2-hydroxy 4-nitro aniline (500 mg, 3.24 mmol) and 3-bromophenylisocyanate (3.24 mmol)according to the procedure in General Method B. The product was purified by dilution with methylene chloride and precipitation with hexanes. Filtering afforded the title compound(0.96g, 87%). EI-MS m/z 350(M−H)−.
