Procedure

Ethyl-4-benzyloxyphenoxyacetate compound (3.50 g, 12.2 mmol) was placed in a PARR bottle along with EtOAc (75 mL), EtOH (75 mL), and 5% Pd/C (1.20 g) and the mixture placed under 40 psi of H2. The reaction was shaken under pressure for 4 hours after which no starting material remained by TLC. The catalyst was removed by filtration through Celite and the filtrate concentrated in vacuo to give 2.35 g (97%) of the desired phenol. MP
