HCID 6422Trifluoroacetic acidSolvent

Procedure

Compound 582 (210 mg, 0.535 mmol) was dissolved in trifluoroacetic acid (2 mL), followed by stirring at room temperature for 1 hour. The solvent was distilled away under reduced pressure, and a saturated aqueous solution of sodium hydrogencarbonate was added to the resulting residue, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (ethyl acetate) to afford the entitled Compound 583 (156 mg, 100%).
