Procedure

To an ice-bath cooled solution of Intermediate 103e (97 mg, 0.13 mmol) in DCM (2 mL) was added DIPEA (58 μL, 0.32 mmol) followed by methanesulfonyl chloride (22 μL, 0.27 mmol). The reaction mixture was stirred for 2 h then partitioned between DCM and water. The aqueous phase was extracted with DCM (×3) and the combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo to afford the title compound (130 mg, quantitative). LCMS (Method 1): Rt 3.69 min, m/z 759 [MH+].
