Versuchsvorschrift

A solution of the product from Step A (0.0703 mmol) in methanol (2 mL) and water (0.1 mL) was treated with potassium carbonate (0.049 g; 0.351 mmol) at room temperature. The reaction mixture was stirred a room temperature until the reaction was judged complete by TLC analysis. The reaction mixture was then 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: 487.0 (M+1), 489.0 (M+3); Rt=5.03 min.
