실험 절차

3.0 g (17.5 mmol) of 2-amino-5-chlorobenzoic acid and 3.95 g (35.0 mmol) of chloroacetyl chloride were heated under reflux in 60 mL of toluene for 1 hour. Thereafter, the solvent was distilled off under reduced pressure, and H2O was added to the resulting residue. Solids were collected by filtration to give 4.15 g of 5-chloro-2-[(chloroacetyl)amino]benzoic acid (yield: 96%).
