5-hydroxyindole (1.00 g, 7.29 mmol) and potassium carbonate (1.38 g, 9.94 mmol) were taken up in 20 mL of dimethylformamide (DMF) and stirred at 60° C. for 0.5 hours. Allyl bromide (0.57 mL, 6.62 mmol) was added and the reaction was stirred for an additional 18 hours then cooled and diluted with ethyl acetate. The organic layer was washed with water, brine, dried over magnesium sulfate, filtered, concentrated in vacuo, and the crude residue was purified by flash chromatography on silica gel (10% ethyl acetate/hexane) to provide the title compound.
