Reaction Steps

20% Phosgene in toluene (0.25 mL, 0.48 mmol) and triethylamine (0.11 mL, 0.76 mmol) were added to a solution of 4-fluoro-2-methyl-benzenamine (12 mg, 0.095 mmol) in a mixture of THF (0.30 mL) and DCM (0.10 mL). The reaction was stirred for two hours, then solvents were removed in vacuo and the product used without further purification in the next step.
