実験手順

To an ice-bath cooled solution of Intermediate 108d (105 mg, 0.16 mmol) in DCM (2 mL) was added DIPEA (43 μL, 0.25 mmol) followed by methanesulfonyl chloride (15 μL, 0.20 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 following step without further purification. LCMS (Method 4): Rt 3.09 min, m/z 717 [MH+].
