| Reactant | 3-Methoxyphenyl isocyanate | HCID 87843 | — |
| Reactant | 2-Amino-5-Nitrophenol | HCID 4984721 | — |
| Product | N-(2-Hydroxy-4-nitrophenyl)-N'-(3-methoxyphenyl)urea | HCID 21184674 | 46.2% |
Reaction Steps
N-(2-Hydroxy-4-nitrophenyl)-N′-(3-methoxyphenyl)urea was prepared from 2-hydroxy 4-nitro aniline (154 mg, 1.0 mmol) and 3-methoxyphenylisocyanate(1.0 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 (140 mg, 46%). EI-MS m/z 302(M−H)−.
