Procedure

A solution of sodium sulfite (0.73 g, 7 mmol) dissolved in water (10 mL) was added to a solution of 4-(4-bromomethylbenzyl)-nitrobenzene (1.41 g, 5.6 mmol) in acetonitrile (10 mL). The mixture was stirred and heated under reflux for 2 hours. Solvents were evaporated and dried to give the 4-(4-nitrobenzyl)-phenylmethanesulfonic acid sodium salt as a white powder (2.29 g).
