Tert-butyl 4-(benzyloxy)benzoate → tert-Butyl 4-hydroxybenzoate

Participants

Reaction Steps

0.36 g of 10% palladium on activated carbon were added to a solution of 1.2 g (4.3 mmol) of 4-benzyloxy-benzoic acid tert-butyl ester in 45 mL of ethanol and this mixture was hydrogenated at 20 psi for 3 hours. After filtering over celite and removing the solvent under reduced pressure 0.79 g (95% yield) of 4-hydroxy-benzoic acid tert-butyl ester were obtained.
