Procedure
4-Acetylaminobenzenesulphonyl chloride (7.3 g, 0.03 mol) was added portionwise to a well stirred mixture of aqueous sodium carbonate (21.2 g. in 250 ml of water) and 2-aminomethyl-1-ethylpyrrolidine (4.0 g. 0.03 mol) in chloroform (250 ml) at about 10°. The ice bath used for cooling was removed. After 2 hours the chloroform layer was separated, dried (MgSO4) and then evaporated under reduced pressure to give a gum, which slowly crystallised (11.6 g). Recrystallisation from cold ethanol, followed by recrystallisation from water gave the pure title compound m.p. 94°-96° C..
