Procedure

To a suspension of compound XII (0.109 g, 0.25 mmol) and potassium carbonate (0.138 g, 1 mmol) in anhydrous acetone (4 mL) was added chloroacetone (60 microliters, 0.75 mmol). The reaction mixture was stirred at reflux and a catalytic amount of potasssium iodide was added. After 3 hours, the solids were removed by filtration and washed with dichloromethane. The dichloromethane solvent was combined with the acetone filtrate and the combined solvents removed by evaporation. The resulting residue was purified on a reverse phase C-18 column using 70% acetonitrile (30% water, 0.1% acetic acid) to afford 86 mg of pure (XIII) (67% yield).
