To solution of 4-bromo-2-iodoaniline (18.50 g, 62.08 mmol) in pyridine (120 mL) at −10° C. was added methyl chloroformate (7.50 mL, 97.46 mmol) over 30 min via syringe pump. Reaction was allowed to warm to room temperature and was diluted with H2O (450 mL). Solid which was formed was collected by filtration, washed with H2O and dried in dessicator. Methyl 4-bromo-2-iodophenylcarbamate (21.59 g, 98%) was obtained as colorless solid.
