実験手順

To a solution of compound 7h (2.0 g, 3.65 mmol) in DMF (8 mL) was added Na2CO3 (0.47 g, 4.38 mmol) followed by ethyl 4-bromobutyrate (0.83 mL, 5.48 mmol). The mixture was heated at 95° C. for 1.5 hours, cooled to room temperature, and partitioned between ethyl acetate and H2O. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by column chromatography on silica gel with ethyl acetate/hexanes/triethylamine 500/500/5 to afford compound 7i (1.29 g) as a white solid. MS (CI) m/z 662.2, 664.2 (MH+)
