2,6-Di-tert-butyl-4-nitrophenol → 4-Amino-2,6-di-tert-butylphenol

Participants

Reaction Steps

2,6-di-t-butyl-4-nitrophenol (6.3 g, 25 mmoles) is dissolved in methanol (100 ml), 0.6 g of palladium on carbon (10%) is added and the reaction medium is placed under a hydrogen atmosphere under 2 bars of pressure. The catalyst is filtered out and the solvent is evaporated off under reduced pressure. The residue is taken up in heptane and filtered. In this way 2,6-di-t-butyl-4-aminophenol (2.7 g, 48%) is obtained which will be used without further purification in the following stages. Pink powder. Melting point: 123-124° C.
