反応手順

A solution of 0.050 g (0.106 mmol) of the product from Example 17 in CH2Cl2 (1 mL) at 0° C. was treated with acetyl chloride (8 μL; 0.106 mmol) followed by triethylamine (15 μL; 0.106 mmol). After the addition, the reaction mixture was warmed to RT and stirred for 1 hour. 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: 515.0 (M+1), 517.0 (M+3); Rt=4.94 min.
