Procedure
The urea was prepared from 2-hydroxy 4-nitro aniline (308 mg, 2 mmol) and 2,3-dichloro phenyl isocyanate (2 mmol) by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the title compound (0.5 g, 73%). EI-MS m/z 342 (M+H)+
