실험 절차

A solution of 2.65 mL (52.0 mmol) of bromine in 10 mL of acetic acid was added dropwise over 15 minutes to a solution of 8.89 g (52.0 mmol) of 2-amino-4-chloro-benzoic acid in 60 mL of acetic acid. The mixture was stirred at room temperature for 1 h and poured into 500 grams of ice. The solid was collected by filtration, washed with cold water and dried to produce 11.2 g (86%) of 2-amino-5-bromo-4-chloro-benzoic acid. LCMS: 251 (M+1)+.
