To the suspension of the triethylamine salt of the product of Example 353E (85.26 mg, 0.16 mmol) in N,N-dimethylformamide (1.6 mL) was added triethylamine (48 μL, 0.34 mmol) and then methanesulfonyl chloride (13.3 μL, 0.17 mmol) at room temperature. The solution was stirred at room temperature for 20 minutes and concentrated in vacuo. The residue purified by reverse phase chromatography, eluting with 20% to 95% acetonitrile/0.1% triflouroacetic acid in water to give the title compound (39.86 mg, 49%).
