Reaction Steps

To a 100 mL of anhydrous THF in a 250 mL round bottom flask containing a stirring bar, 2-iodo-4-bromoaniline (2.00 g, 6.70 mmol) was added along with 3-trifluoromethylphenylisocyanate (1.51 g, 7.00 mmol) and 52 mg of pyridine. The resulting solution was heated at 65° C. overnight. THF was removed by rotary evaporation and the product was recrystallized from ethyl acetate to give 3.0 g (92%) of 1-(2-iodo-4-bromophenyl)-3-(3-trifluoromethylphenyl)urea as a white solid.
