실험 절차

The urea was prepared from 2-hydroxy 4-nitro aniline (500 mg, 3.24 mmol) and 2-chloro 6-methyl phenyl isocyanate by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the desired compound (0.31 g, 29%). EI-MS m/z 322 (M+H)+
