Reaction Steps

To a stirred solution of N-acetylsulfanilyl chloride (57.15 g, 0.244 mol) in acetone (500 mL) and H2O (187.5 mL) at 0° C. was added 3-bromopropylamine hydrobromide (25.0 g, 0.114 mol). When a clear solution was obtained, a solution of sodium hydrogencarbonate (44.15 g, 0.526 mol) in H2O (550 mL) was added dropwise, maintaining the internal temperature at 0-5° C. When the addition was completed, the reaction mixture was heated at 50° C. for 5 h, then cooled to room temperature and poured into ice H2O with stirring. After stirring at 5° C. for 4 h, the suspension was filtered and the filter cake was washed with H2O and dried in vacuo to give 34.6 g (90%). An additional reaction was performed to give an additional 63.7 g of similar material.
