Ammonium formate → HCID 10638671, compound

Participants

Reaction Steps

3'-Benzyloxy-8-ethoxycarbonylflavone (1 eq.) was dissolved in methanol, followed by the addition of ammonium formate (8 eq.) and 10% wt/wt palladium-carbon. The resulting mixture was refluxed. Subsequent to the completion of the reaction, the catalyst was eliminated by hot filtration. The mother liquor was allowed to cool down to room temperature. The resulting crystals were collected by filtration, washed with water and then recrystallized from DMF-ethanol, whereby the title compound was obtained (yield: 51%).
