Methanesulfonyl Chloride (1.5 eq, 0.003 g) was added to a solution of the title compound of Example 7 (0.005 g, 0.018 mmol) in CH2Cl2 (0.045 M, 0.4 mL) and pyridine (0.045 M, 0.4 mL). The mixture stirred at 22° C. for 24 hours and concentrated under reduced pressure. Silica gel chromatography (triethylamine/methanol/CH2Cl2; 1:5:94) afforded the title compound (1.7 mg) in 30% yield.
