Participants

Reaction Steps

The product of Example 131 (100 mg, 0.23 mmol) in CH2Cl2 (4 mL) was stirred under Ar at 23°. Triethylamine (0.1 mL) was added followed by the addition of a solution of methanesulfonyl chloride (29 mg, 0.25 mmol) in CH2Cl2 (1 mL). The solvents were removed in vacuo, and the residue was partitioned between EtOAc and H2O. The organic phase was washed with H2O, satd aq NaCl, dried over anhyd Na2SO4, filtered and evaporated to give the crude product. Flash chromatography eluted with 0-10% EtOAc/CH2Cl2 gave the title compound as a white-amorphous solid. mp 95-99°, LC MS m/z=505 (MH+) Retention time=2.02 min.
