3-(4-Benzyloxy-phenyl)-2-ethoxy-propionic acid methyl ester → 2-Ethoxy-3-(4-hydroxy-phenyl)-propionic acid methyl ester

Participants

Reaction Steps

A suspension of methyl 3-[4-benzyloxyphenyl)-2-ethoxypropanoate (3.7 g, 11.78 mmol; preparation 2) and 10% Pd-C (0.37 g) in ethyl acetate (50 mL) was stirred at 25° C. under 60 psi hydrogen pressure for 24 h. The catalyst was filtered and the solvent was evaporated under reduced pressure. The residue was chromatographed over silica gel using a mixture of ethyl acetate and pet. ether (2:8) as an eluent to afford the title compound (2.2 g, 84%) as an oil.
