Sodium Sulfite → 6-chloro-5-[4-(3-hydroxypropyl)phenyl]-1H-indole-3-carboxylic acid

Participants

Reaction Steps

To 6-chloro-5-[4-(3-hydroxypropyl)phenyl]-1H-indole-3-carbaldehyde (40 mg, 0.13 mmol) in 2-methyl-2-butene/t-butanol/water (v/v/v=1/1/1, 6 mL) was added sodium dihydrogen phosphate (30.5 mg, 0.254 mmol) and sodium chlorite (23 mg, 0.25 mmol) at room temperature. The resulting mixture was stirred at room temperature for 14 hours. The reaction mixture was added sodium sulfite (0.254 mmol), diluted with water, extracted with EtOAc, then concentrated in vacuo and purified via preparative HPLC to give the title compound (6.0 mg, 14% yield).
