Participants

Reaction Steps

To a solution of (E)-3-(4-benzenesulfonyl-2-bromo-phenyl)-acrylic acid methyl ester (8.52 g) in a mixture EtOH/THF (2/1, 150 mL) was added under N2 atmosphere PtO2 (0.45 g). A balloon filled with H2 was set up and N2 was replaced with H2, the reaction was then stirred for 4 h 30 min. The mixture was filtered and the filtrate was evaporated in vacuo. The residue was purified via flash chromatography (hexane/EtOAc, 85/15) affording 3-(4-benzenesulfonyl-2-bromo-phenyl)-propionic acid methyl ester (6.73 g).
