| 生成物 | N-(2-hydroxy-4-trifluoromethylphenyl) N'-(2-phenylphenyl)urea | HCID 22011313 | 64% |
反応手順
The urea was prepared from 2-hydroxy 4-trifluoromethyl aniline (example 7a, 0.171 g, 1 mmol)) and 2-phenyl phenyl isocyanate by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the desired compound (0.24 g, 64%). EI-MS m/z 373 (M+H)+
