Participants

Reaction Steps

2-Ethoxy-3-{4-[2-(4-methanesulfonyloxyphenyl)ethoxy]phenyl}acrylic acid ethyl ester (1.47 g; 3.38 mmole) was hydrogenated for 3 hours at atmospheric pressure in ethyl acetate (50 ml) using Pd/C (0.74 g, 5%) as catalyst. The reaction mixture was filtered through celite, dried (magnesium sulfate) and the solvent was evaporated in vacuo to give 1.44 g (yield 98%) of 2-ethoxy-3-[4-(2-{4-methanesulfonyloxy-phenyl}ethoxy)phenyl]propanoic acid ethyl ester.
