Procedure

A solution of 2-bromo-1-(4-hydroxy-3-methylphenyl)ethanone (200 mg, 0.87 mmol) in formamide (10 mL) was heated to 110° C. for 24 h. The excess formamide was removed by distillation under reduced pressure. The resulting residue was partitioned between a pH 7.0 buffer solution (10 mL) and EtOAc (50 mL). The organic layer was washed with water (10 mL) and brine (10 mL), dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (Hexane:EtOAc, 1:1) to yield the title compound (51 mg, 33% yield).
