Reaction Steps
To a solution of 5-acetyl-2-chloro-benzoic acid methyl ester (100 mg, 0.47 mmol) in glacial acetic acid (5 mL) was added bromine (0.05 mL, 0.94 mmol). The mixture was stirred at room temperature for 2 h. Hydrobromic acid-acetic acid (2 drops, 30%) was added and the mixture was stirred for 10 minutes. The mixture was concentrated in vacuo to afford the title compound (140 mg).
