実験手順
To a solution of imidazo[1,2-a]pyridin-2-ylmethanol (3.0 g, 20 mmol) in EtOH (50 mL) was added manganese (IV) oxide (8.8 g, 100 mmol). The mixture was refluxed for 2 days. After cooling to room temperature, the mixture was filtered through Celite, and the filtrate was concentrated. The residue was purified by reverse phase column chromatography (eluting with acetonitrile in water 25% v/v, with 0.01% NH3. H2O) to afford the title compound (0.45 g, 15% yield) as a yellow solid. ESI MS: m/z 147 [M+H]+.
