Procedure
To a −10° C. solution of 3-(3-hydroxy-phenyl)-propionic acid ethyl ester (2.0 g, 10.31 mmol) in chloroform (0.2 M, 51 mL) was added N-bromosuccinimide (1.93 g, 10.83 mmol). After stirring at RT overnight, the solution was concentrated in vacuo and purified by flash column chromatography (SiO2, 5% to 15% ethyl acetate/hexanes) to give the product as a colorless oil (0.45 g, 16%).
