To a suspension of sodium p-hydroxybenzenesulfonate (40 g, 0.17 mole) in a solution of NaOH (9.61 g, 0.24 mole) and H2O (55 ml), a solution of benzyl chloride (27.6 g, 0.22 mole) in ethanol (35 ml) was added dropwise, and continued to stir for 5 hours under reflux. After standing at room temperature overnight, the precipitate was filtered, washed with H2O and dried to afford 35.2 g of sodium p-benzyloxybenzenesulfonate as white crystals.
