Procedure

To a solution of potassium carbonate (2 kg) in acetonitrile (5000 ml) is added 2-[(2-(4-fluorobenzoyl)phenyl)amino]-3-(4-hydroxyphenyl)-propionic acid methyl ester (581 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-(4-fluorobenzoyl)phenyl)amino]-3-[4-(2-bromoethoxy)-phenyl]-propionic acid methyl ester (429 g, 58%).
