Ammonium formate → HCID 23071160, compound

Participants

Reaction Steps

To a solution of 2-(7-(benzyloxy)-1H-indol-3-yl)ethanol (6.31 g, 23.6 mmol) in ethanol (130 mL) are added ammonium formate (6.3 g, 99.9 mmol) and 10% palladium on carbon (50% wet, 555 mg), and the mixture is refluxed for one hour. The reaction solution is cooled to room temperature, and filtered through celite. The solvent is evaporated, and the obtained crude product is purified by silica gel column chromatography (n-hexane:ethyl acetate=1:1) to give 3-(2-hydroxyethyl)-1H-indol-7-ol (3.19 g, 18.0 mmol, yield: 76%).
