HCID 139386(2-Bromophenyl)ureaYield 134.9%

Procedure

The urea was synthesized from 2-(2-thiophene sulfonyl amino) aniline(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 desired compound(0.29 g, 64%). EI-MS m/z 450(M−H)−.
