Procedure

Methane sulfonylchloride (46.0 μL, 0.59 mmol) was added to an ice cold solution of Example 39 (187 mg, 0.28 mmol) and DIPEA (122 μl, 0.70 mmol) in DCM (3.0 mL). After 2.5 h the reaction was partitioned between DCM and water. The aqueous layer was then extracted with DCM (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo to give the title compound (208 mg, 99%). LCMS (Method 2): Rt 3.38 min, m/z 743 [MH+].
