Procedure

Compound 560 (428 mg, 0.849 mmol) was dissolved in dichloromethane (3 mL), and trifluoroacetic acid (3 mL) was added thereto at 0° C., followed by stirring at room temperature for 3 hours. The reaction mixture was concentrated under reduced pressure, and a saturated aqueous solution of sodium hydrogencarbonate was added to the resulting residue, followed by extraction with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was reslurried with diethyl ether to afford the entitled Compound 561 (263 mg, 77%).
