実験手順

TFA (1 ml) was added to a chloroform solution (2 ml) containing tert-butyl(5-(5-methylfuran-2-yl)pyridin-3-yl)carbamate (61 mg) obtained in the 1st step, stirring at room temperature for 2 hours. The solvent was distilled away under reduced pressure, the obtained residue was dissolved in chloroform, and the resultant was washed with water and a saturated aqueous sodium hydrogen carbonate solution. Subsequently, the aqueous layers were combined, followed by extraction with chloroform (×2). The organic layers was combined and dried over anhydrous sodium sulfate. The solvent was distilled away from the obtained organic layers under reduced pressure, and a white solid of 5-(5-methylfuran-2-yl)pyridin-3-amine (46 mg) was thus obtained.
