실험 절차

To a suspension of trimethylsulfoxonium iodide (234 mg) in DMSO (3 mL) stirred under nitrogen at 20° C. was added NaHMDS (1.0 mol/L in THF, 1.0 mL) dropwise during 5 mins. The reaction mixture was stirred at this temperature for 15 mins. A solution of methyl (2Z)-3-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]-2-propenoate (D63) (120 mg) in DMSO was added dropwise. After addition was complete, the reaction was stirred at room temperature for 1.5 h, and then warmed to 50° C. for 4 h. The reaction mixture was cooled to room temperature and partitioned between ethyl acetate (25 mL) and water (25 mL). The organic phase was washed with water, aqueous HCl (2 M) and brine, dried over sodium sulphate and evaporated to afford methyl-2-[7-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]cyclopropanecarboxylate (D65) (100 mg). MS (ES): C25H24ClN3O4 requires 465. found 466.2 (M+H+).
