Procedure

To a solution of Example 98 (0.2 g) in THF (5 mL) was added triethylamine (228 μL) and methanesulfonyl chloride (126 μL) and the solution was heated at reflux for 6 hours. After evaporation of THF, the residue was taken up in CH2Cl2, washed with water and dried over Na2SO4. After evaporation of CH2Cl2, the residue was purified by radial chromatography eluting with CH2Cl2 /MeOH (95/5) to give the title compound as a brown powder (30 mg) m.p.:188° C.
