Procedure

To an ice-bath cooled solution of Intermediate 124b (174 mg, 0.26 mmol) in DCM (3 mL) was added DIPEA (182 μL, 1.0 mmol) followed by methanesulfonyl chloride (41 μL, 0.52 mmol). The reaction mixture was stirred for 1 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 following step without further purification. LCMS (Method 4): Rt 3.47 min, m/z 746 [MH+].
