Reaction Steps
The reaction mixture is prepared in an autoclave by adding 0.04 mole (15 g) of 2-nitro-4,5-dibenzyloxyphenylacetonitrile, 1.5 g of palladium at a concentration of 10% on charcoal and 1.5 g of charcoal to 120 ml of ethanol containing 3 ml of water. These are heated to 80° C. for 2 hours, with stirring, under a hydrogen pressure of 4.105Pa. After cooling, the reaction mixture, which is treated in the same manner as previously, produces 5,6-dihydroxyindole in an equivalent yield.
