実験手順
To a solution of compound 41 (85.2 mg, 0.15 mmol) in DCM (2 mL) was added neat trifluoroacetic acid (0.7 mL). The reaction was allowed to stir at room temperature for 2 h then concentrated, diluted with AcOEt, washed with saturated aqueous NaHCO3, brine, dried over MgSO4, filtered and concentrated to give title compound 42 (38 mg, 54% yield).
