Reaction Steps

6-Benzyloxy 5-butoxy indole (4 g, 0.0135 mole) is hydrogenated under 50 atmospheres of hydrogen in a reactor with 40 ml of ethanol and 0.6 g 10% palladium on carbon for 3 hours. After filtration and evaporation of the solvent, the residue is recrystallized in a mixture of benzene-hexane to produce 5-butoxy 6-hydroxy indole (2.5 g, yield 90%).
