1,2-Dibromoethane → HCID 58960092, compound

Participants

Reaction Steps

To a solution of potassium carbonate (2 kg) in acetonitrile (5000 ml) is added 2-((2-benzoylphenyl)amino)-3-(4-hydroxyphenyl)-propionic acid methyl ester (555 g, 1.48 mol) and 1,2-dibromoethane (1000 ml). Then the mixture is stirred at room temperature for 24 hours. After that, the reaction mixture is filtered, and then the filtrate is evaporated under a vacuum. The crude product is purified by silica gel chromatography using hexane/EtOAc (4:1) as eluent to give 2-((2-benzoylphenyl)amino)-3-[4-(2-bromoethoxy)-phenyl]-propionic acid methyl ester (442 g, 62%).
