Reaction Steps

A mixture of N-[3-(4-Amino-3-propylaminomethyl-phenylsulfanyl)-phenyl]-benzenesulfonamide (0.0016 mol) and cyanogen bromide (0.0020 mol) in ethanol (q.s.) was reacted overnight at room temperature and then the organic solvent (EtOH) was evaporated. The obtained concentrate was warmed in EtOH and then cooled. The mixture was filtered and the collected residue was recrystallized from EtOH to yield the title compound as a solid.
