Procedure

To a 0 ° C. solution of 3-(3-hydroxy-phenyl)-propionic acid ethyl ester (1.0 g, 5.15 mmol) in diethyl ether (50 ml) was added sulfuryl chloride (0.493 mL, 6.18 mmol). After 2.5 h at 0° C., the reaction was quenched with sat. sodium carbonate (50 ml). The aqueous layer was extracted with ethyl acetate. The organic portions were combined and dried with magnesium sulfate. The solvent was removed in vacuo to afford crude product, which was purified by column chromatography (10% ethyl acetate/hexanes). The title compound was obtained as colorless oil (0.73 g, yield 62%): 1H NMR (CDCl3) δ 6.96 (d, J=10.1 Hz, 1H); 6.54( d, J=2.97 Hz,1H); 6.46 (dd, J=8.6, 3.0 Hz,1H); 3.96 (dd, J=12.5 5.3 Hz, 2H); 2.82-2.78 (m, 2H); 1.08-1.00 (m, 3H).
