実験手順

Methyl 2-acetyl-1-benzofuran-6-carboxylate (155 mg, 0.71 mmol) is dissolved in MeOH (3 ml) and H2O (0.5 ml). 2N NaOH (0.39 ml, 0.78 mmol) is added drop-wise, and the reaction is stirred overnight. The volatiles are removed in vacuo, and the residue is dissolved in H2O (3 ml). Concentrated HCl is used to adjust the pH to 3, and the resulting precipitate is isolated via filtration and dried overnight to afford 135 g (93%) of 2-acetyl-1-benzofuran-6-carboxylic acid as a yellow solid. MS for C11H8O4, (ESI−) m/z: 202.7 (M−H)−.
