Reaction Steps

Piperidine (0.0114 Mol) is added to a solution of 4-acetamidophenylsulfonyl chloride (1.34 g, 0.0057 mol) in dioxane (5 mL). The mixture is heated for 1 hour at 80° C., then part of the solvent is removed by evaporation at reduced pressure, and water is added until precipitation of the resulting sulfonamide. The product is collected by filtration as a white solid (52.14% yield) and used without further purification. m.p. 137° C.-139° C. 1H NMR (acetone-d6): δ 1.35-1.43 (m, 2H); 1.52-1.63 (m, 4H); 2.17 (s, 3H); 2.89-2.95 (m, 4H); 7.68-7.70 (d, 2H, J=7); 7.90-7.92 (d, 2H, J=7); 9.55 (bs, 1H). In a similar fashion, the following sulfonamides were prepared:
