Product 1

HCID 139386(2-Bromophenyl)urea

Procedure

The urea was prepared from 3-hydroxy 4-amino benzoic acid (3.69 g, 24 mmol) and 2-bromophenylisocyanate(24 mmol) by general Method B. It was purified by dilution of the DMF solution with methylene chloride and precipitation with hexane(4.0 g, 48%). EI-MS m/z 351(M+H)+.
