実験手順

A solution of 6-fluoro-5-[4-(hydroxymethyl)phenyl]-1H-indole-3-carbaldehyde (65 mg, 0.24 mmol) in acetonitrile (3 mL) and tert-butanol (3 mL) was treated with 2-methyl-2-butene (2 mL, 18.4 mmol) and cooled to 0° C. A solution of sodium chlorite (410 mg, 4.9 mmol) and sodium dihydrogen phosphate monohydrate (684 mg, 4.96 mmol) in water (3 mL) was added dropwise via an addition funnel. The reaction mixture was warmed to room temperature and stirred for 65 hours. The reaction was partially evaporated in vacuo, and partitioned between water and ethyl acetate. The organic phase was concentrated in vacuo. The crude material was purified using reverse-phase chromatography to give the title compound (20.4 mg).
