Procedure
3-(4-Benzyloxy-3-methoxyphenyl)-2-ethoxyacrylic acid ethyl ester (5.5 g, 15.4 mmole) was dissolved in ethyl acetate and hydrogenated using Pd/C (dry, 5%). The reaction mixture was filtered through celite. Evaporation of the filtrate gave 4 g (97% yield) of 3-(4-benzyloxy-3-methoxyphenyl)-2-ethoxypropanoic acid ethyl ester.
