実験手順
113 mg (0.6 mmol) 2-(2-nitro-phenyl)-furan are dissolved in 2 ml of ethanol and combined with 6 mg palladium on activated charcoal (10% Pd). 110 μl of a 35% aqueous hydrazine solution are added to this suspension and the reaction mixture is stirred for 20 h under reflux conditions. The catalyst is suction filtered, the filtrate is combined with 25 ml of water and adjusted to pH 5. This mixture is extracted three times with 10 ml of ethyl acetate. The combined organic phases are dried and the solvent is eliminated in vacuo.
