Reaction Steps
To a suspension of sodium hydride (ca 60%, 21 mg, 0.52 mmol) in DMSO (1 mL) was added trimethylsulfoxonium iodide (115 mg, 0.52 mmol), and the mixture was stirred at room temperature for 20 minutes. Then, ethyl (E)-3-(1-methyl-1H-indol-3-yl)acrylate (Synlett, (9), 1319-1322 (2006)) (100 mg, 0.44 mmol) was added to the mixture, and the mixture was stirred at room temperature for 1 hour and at 60° C. for 20 hours. After cooling to room temperature, the mixture was poured into water (30 mL), and the aqueous phase was extracted with ethyl acetate (twice). The combined organic layers were dried over Magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (7:1) to give 23 mg (21% yield) of the title compound as a pale yellow oil:
