Procedure

A solution of 1-bromo-2-(2-bromoethyl)benzene (6.23 g, 23.6 mmol) in ethanol (20.5 mL) was added to a solution of sodium sulfite (3.12 g, 24.7 mmol) in water (25.0 mL). The mixture was heated at 100° C. for 24 hours. The reaction mixture was filtered, and the filtrate was then left to stand at 3° C. overnight. The resulting white crystals were collected by filtration and dried to give sodium 2-(2-bromo-phenyl)ethanesulfonate (4.00 g, 59%).
