Procedure

To a solution of Intermediate 94a (169 mg, 0.64 mmol) and Et3N (265 μL, 1.91 mmol) in DCM (6 mL) was added triisopropylsilyl trifluoromethanesulfonate (189 pt, 0.70 mmol). The solution was stirred for 2.5 h, then diluted with water and extracted with DCM. The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-5% (2M NH3 in MeOH) in DCM, to give the title compound as a pale brown gum (242 mg, 90%). LCMS (Method 3): Rt 2.93 min, m/z 422 [MH+].
