Versuchsvorschrift

As an additional variation of the reaction sequence, the 4-(2-bromoethyl) benzenesulfonamide produced as in Example I was reacted with benzenesulfonyl chloride and sodium hydroxide and then acidified to produce N-benzenesulfonyl-4-(2-bromoethyl) benzenesulfonamide. Recrystallization of a small portion from toluene gave a white solid, having a melting point of 148°-150° C. and a neutralization equivalent of 405 (theory 404).
