Compound 25 (1.0 equiv.) was dissolved in MeCN (40 mL) and treated with anhydrous potassium carbonate (2.0 equiv.) at room temperature. To this mixture diisopropyl(bromomethyl)phosphonate (1.2 equiv.) was added via a micro syringe. After being stirred for 4 Hours at 60° C., the reaction mixture was concentrated under reduced pressure. The crude residue was diluted by ethyl acetate (50 mL), and washed with water (2×10 mL). Then it was dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (1:4 v/v ethyl acetate/petroleum ether) to provide a yellow solid (235.2 mg, 41% yield).
