実験手順

Methyl 2-(diethoxymethyl)-1-benzofuran-6-carboxylate (2.71 g, 9.7 mmol) is treated drop-wise with formic acid (20 ml, 530 mmol) and water (5.5 ml). The reaction is stirred overnight at RT, diluted with water (50 ml), and the brown slurry is filtered. The cake is dried overnight to afford 1.86 g (94%) of methyl 2-formyl-1-benzofuran-6-carboxylate as an amber solid. 1H NMR (400 MHz, DMSO-d6): δ 3.91, 8.03, 8.28, 9.92 ppm.
