実験手順

To a solution of sodium hydride (60%, 254 mg, 6.35 mmol) in 15 mL tetrahydrofuran (THF) was added 5-allyloxyindole (Step A; 1.0 g, 5.77 mmol) in 5 mL THF and the mixture was stirred for 1 hour at ambient temperature. Neopentyl iodide (0.69 mL, 6.35 mmol) was added and the reaction heated to reflux for 21 hours. After cooling, the reaction was quenched with saturated aqueous ammonium chloride and extracted with ethyl acetate. The organic layer was washed with water, brine, dried over magnesium sulfate, filtered, concentrated in vacuo, and the crude residue purified by flash chromatography on silica gel (15% ethyl acetate/hexane) to provide the title compound.
