Reaction Steps

To a stirred solution of sodium ethoxide (23.8 g) in ethanol (anhydrous, 400 ml) is added toluene-4-sulfonamide (60 g) around 50 C. The formed slurry is heated up to reflux for 2 hours and then cooled to 20° C. The precipitated solid is collected by filtration, rinsed with anhydrous ethanol and dried under vacuum with nitrogen flow to give toluene-4-sulfonamide monosodium salt (61.3 g, yield: 90.6%).
