A mixture of 0.25 g (0.99 mmol) of 7-Carbomethoxybenzofuran and 0.1 mL of K2CO3 (1N in water) in 6 mL of methanol was stirred at it for 24 h. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, hexanes: ethyl acetate, 4:1, then ethyl acetate: methanol, 9:1) to give 0.15 g of the title compound.
