A mixture of Intermediate 55eB (26.0 mg, 0.30 mmol), methanesulfonyl chloride (70.0 μL, 0.90 mmol) and DIPEA (208 μL, 1.20 mmol) in DCM (8 mL) was stirred at RT for 1 h. The reaction mixture was partitioned between DCM and water. The organic layer was washed with brine, separated through a phase separating cartridge and concentrated in vacuo to afford the title compound (275 mg, 97%). LCMS (Method 3): Rt 5.23 min, m/z 943 [MH+].
