Procedure

To a solution of homoveratrole (136.4 g, 1.1 mol) in chloroform (1.2 L) and dichloromethane (300 mL) was slowly added a solution of bromine (66 mL, 1.28 mol, 1.2 eq.) in carbon tetrachloride (250 mL). After 5 hours the reaction mixture was neutralized to pH7 with an aqueous solution of sodium hydroxide and the aqueous layer was extracted with chloroform. The combined organic layer was dried over sodium sulfate, filtered, and the volatiles were removed in vacuo, affording the title compound as a light brown solid, m.p.: 92-98° C.
