Procedure

To an ice-bath cooled solution of Intermediate 141b (132 mg, 0.19 mmol) in DCM (2.0 mL) was added DIPEA (135 μL, 0.78 mmol) followed by methanesulfonyl chloride (30 μL, 0.39 mmol). The reaction mixture was stirred for 2 h and then quenched with 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 (Quantitative). Product used in the subsequent step without further purification. LCMS (Method 4): Rt 3.30 min, m/z 759 [MH+].
