Reaction Steps

2-Phthalimidoethanesulfonyl chloride (2.0 g) was added portion wise to a solution of 0.5 M of ammonia in dioxane (15 ml) and the solution obtained this way was stirred at room temperature. After 48 hours the reaction mixture was poured in water (50 ml) causing the title compound to precipitate. The product was collected by filtration. Yield: 1.52 g (83%) of a solid. 1H-NMR (DMSO-δ6) δ (ppm) 7.92-713 (m, 4H), 7.06 (s, 2H), 6.88-3.93 (m, 2H), 3.37-3.30 (m, 2H).
