반응 단계
A mixture of methyl bromoacetate (1.53 g, 10 mmol), 2-hydroxy-4-methoxybenzaldehyde (1.52 g, 10 mmol) and Cs2CO3 (6.5 g, 20 mmol) in DMF (100 mL) was stirred vigorously at 50° C. for 3 hrs and then at 150° C. for 5 min. The reaction was cooled, diluted with ethyl acetate and washed with water. The organic phase was dried and concentrated to give essentially pure 6-methoxy-benzofuran-2-carboxylic acid methyl ester as a solid.
