Reaction Steps

Methyl 2-(aminocarbonyl)-1-benzofuran-6-carboxylate(164 mg, 0.75 mmol) is dissolved in MeOH (5 mL) and water (1 mL), treated drop-wise with 2N NaOH (450 μL, 0.9 mmol) and monitored by TLC. The volatiles are removed in vacuo, and the resulting tan solid is dissolved in water (5 mL) and acidified to pH 3 with concentrated HCl. The resulting solid is collected via filtration and dried in a vacuum oven with heat 50° C. to afford 142 mg (93%) of 2-(aminocarbonyl)-1-benzofuran-6-carboxylic acid as an orange solid. HRMS (EI) calcd for C10H7NO4: 205.0375, found 205.0378 (M)+.
