실험 절차

To a solution of 4-bromo-3-chloro-2-fluoroaniline (15.0 g) in ethyl acetate (200 mL) was added dropwise acetic anhydride (7.57 mL) at 0° C. Then, pyridine (10.8 mL) was added dropwise, and the mixture was stirred at room temperature overnight. The mixture was diluted with ethyl acetate, washed with water and saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained solid was washed with hexane to give the title compound as a colorless solid (yield: 17.1 g, 96%).
