실험 절차
A solution of Example 557A (0.587 g, 1.1 mmol) in CH2Cl2 (10 mL) was treated with TFA (2 mL). The reaction was stirred for 3 hours, concentrated, and diluted with CH2Cl2. The organic layer was washed with pH 7 buffer solution, dried (MgSO4), filtered, and concentrated to provide the desired product. (MS (ESI(+)) m/e 458 (M+H)+.
