A mixture of 2-bromo-N-(3-bromo-2-hydroxyphenyl)propionamide (4.70 g, 14.6 mmol) and potassium carbonate (2.01 g, 14.6 mmol) in N,N-dimethylformamide (100 ml) was stirred at room temperature for 15 h. The mixture was poured into water and extracted with ether. The extract was washed with brine, dried over magnesium sulfate and concentrated under vacuum. The residue was purified by column chromatography eluting with 20% ethyl acetate/n-hexane to afford 2.12 g (60%) of the title compound.
