Procedure

A solution of 0.030 g (0.0696 mmol)of the product from Example 5 in CH2Cl2 (1 mL) cooled to 0° C. was treated with methanesulfonyl chloride (5 μL; 0.0696 mmol), followed by triethylamine (30 μL; 0.209 mmol). The reaction mixture was allowed to warm to room temperature and stirred for 2 h. The reaction was quenched with saturated NaHCO3 solution. The reaction mixture was partitioned between ethyl acetate and saturated NaHCO3 solution. The organic layer was washed twice with saturated NaHCO3 solution, brine, dried (Na2SO4), filtered, and concentrated in vacuo. Purification by MPLC (silica gel; 0% to 20% ethyl acetate:hexane gradient) gave the title compound. HPLC/MS: 586.9 (M+1), 588.9 (M+3); Rt=4.16 min.
