2,4-dibromo-1-isocyanatobenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The urea was prepared from 4-nitro 2-hydroxy aniline (308 mg, 2 mmol) and 2,4-dibromo 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 (0.34 g, 39%). EI-MS m/z 430 (M+H)+ It was purified by dilution with methylene chloride and precipitation with hexane Filtering

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
