Participants

Reaction Steps

To a stirring solution of 2-{4-[(3,5-Dimethyl-phenylcarbamoyl)-hydroxy-methyl]-phenoxy}-2-methyl-propionic acid ethyl ester (1.4 g, 3.6 mmol), in dry diethyl ether (10 mL) under nitrogen at 0° C. was added lead tribromide in methylene chloride (4.4 mL, 4.4 mmol) drop wise. The reaction mixture was further stirred at room temperature for 4 hr and concentrated. Water (100 mL) added and the product extracted with Ethyl acetate (3×50 mL), dried and evaporated to yield 1.0 g of 2-{4-[bromo-(3,5-dimethyl-phenylcarbamoyl)-ethoxy-methyl]-phenoxy}-2-methyl-propionic acid ethyl ester.
