実験手順

A mixture of 6-chloro-5-[(2R)-2-(hydroxymethyl)-2,3-dihydro-1,4-benzodioxin-6-yl]-1H-indole-3-carbaldehyde (1.0 g, 2.9 mmol), sodium chlorite (5.28 g, 58.3 mmol), sodium dihydrogen phosphate (9.06 g, 58.1 mmol) in 2-methyl-2-butene (10 mL), water (10 mL), t-butanol (10 mL) and acetonitrile (10 mL) was stirred overnight at room temperature. The mixture was quenched with saturated aqueous sodium bisulfite. Water (50 mL) and methylene chloride (50 mL) was added. The aqueous layer was extracted with methylene chloride (50 mL×3). The combined organic layer was dried over sodium sulfate, filtered and evaporated to give residue which was purified by reverse phase HPLC to give the title compound (105 mg, 14.3% yield).
