Procedure

To a solution of compound 4a (30 mg, 0.048 mmol) in DCM (1 mL) was added TFA (0.1 mL, 1.3 mmol) and stirred at room temperature for 1.5 hours. After concentration, the residue was taken up in DCM and saturated aq. NaHCO3 was added. The aq. layer was extracted with DCM. Combined organic extracts were dried over Na2SO4 and concentrated to give compound 4b. MS (CI) m/z 528.0, 530.0 (MH+).
