Reaction Steps

1,2-Dibromoethane (5.0 ml, 58 mmol) was added to a solution of sodium hydroxide (2.5 g, 63 mmol) and 2,6-dibromophenol (14.5 g, 57.6 mmol) in 45 ml of water. The mixture was stirred under reflux for 20 hours and then extracted with ether. The combined organic layers was dried over Na2SO4, filtered and concentrated to give colorless oil. Silica gel chromatography using a gradient of ethyl acetate in hexanes to afforded 1,3-dibromo-2-(2-bromo-ethoxy)-benzene (11.55 g, 57% yield) as a colorless oil.
