Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1-Amino-2-naphthol | HCID 14535 | — |
| Reactant | 2-Bromophenyl isocyanate | HCID 137097 | — |
| Product | N-(2-hydroxynaphthyl) N'-(2-bromo phenyl) urea | HCID 22011318 | 8.4% |
Reaction Steps
The urea was prepared from 1-amino 2-hydroxy naphthalene (195 mg, 1 mmol) and 2-bromo phenyl isocyanate (1 mmol) by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the title compound (0.030 g, 8%). EI-MS m/z 357 (M+H)+
