Reaction Steps

To a solution of 2-trifluoromethoxy-5-bromo-phenylamine (5.12 g, 20 mmol) in EtOH (50 mL) at 0° C. was added a solution of acetic anhydride (4.7 mL, 50 mmol) in EtOH (10 mL). The mixture was stirred at room temperature overnight. The solvent was evaporated to dryness and the solid was tritured with diethyl ether and filtered to give 5.64 g (95% yield) of N-(5-bromo-2-trifluoromethoxy-phenyl)-acetamide.
