To the solution of 2.8 g (0.020 mol) of 3-morpholinopropylamine in 15 ml of acetone, the solution of 3.3 g (0.024 mol) of potassium carbonate in 3 ml of water was added under stirring. To this mixture, 5 g (0.021 mol) of 4-acetamidobenzenesulphonyl chloride XII was added portionwise at the room temperature for 15 min. The mixture was then stirred at the room temperature for another 2 hours. One half of the solvent volume was distilled off from the mixture, the mixture was cooled to 0° C., Obtained solid was separated, washed 3 times with 5 ml of ice water and dried. Afforded 4.2 g (62%) of 4-acetamido-N-(3-morpholinopropyl)benzenesulphonamide XIII, colourless solid, m.p. 97-98° C.
