실험 절차

To a solution of 2-[2-(5-benzyloxy-1H-indol-3-yl)ethyl]isoindole-1,3-dione (800 mg in a mixture of dry 25 mL tetrahydrofuran and 25 mL dry chloroform) at 0° C. was added pyridinium hydrobromide perbromide (666 mg) and the mixture stirred at 0° C. After 23 minutes the reaction was quenched by the addition of saturated sodium bicarbonate and extracted with ethyl acetate. The organic portion was washed with saturated sodium bicarbonate (3×) and 0.3M sodium bisulfate (3×) then dried over magnesium sulfate. Purification of the concentrate by flash chromatography on silica gel (hexane:ethyl acetate, 7:2) followed by repurification by flash chromatography on silica gel (methylene chloride) gave the title compound (632 mg).
