실험 절차

The tert-butyl 2-[4-(6-chloro-3-formyl-1H-indol-5-yl)phenyl]pyrrolidine-1-carboxylate (160 mg, 0.377 mmol) was dissolved in acetonitrile (9 mL) and warm t-butanol (9 mL) followed by the addition of 2-methyl-2-butene (6.00 mL, 56.5 mmol) and cooled to 0° C. followed by the addition of an aqueous solution of sodium chlorite (763 mg, 11.3 mmol) and sodium phosphate (monobasic and monohydrate, 1.56 g, 11.3 mmol) in water (5 mL) dropwise via additional funnel. The ice bath was removed and the mixture was allowed to warm to room temperature. The suspension was stirred overnight. To the suspension was added sodium sulfite (1.43 g, 11.3 mmol) in water (3 mL) and the resultant mixture concentrated to remove the organic solvent followed by extraction three times with ethyl acetate (15 mL). The combined organic layers were dried over sodium sulfate, filtered, and concentrated to afford crude product which was purified by reverse phase HPLC to afford the title compound (140 mg, 84.2% yield).
