title: [Synthesis of p-aminobenzenesulfonyldiazine].
abstract: New sulfones were synthesized; these are analogues of bis-(4-aminophenyl)sulfone (DDS) but contain, instead of one benzene nucleus, a heterocycle that is a pyrimidine, pyrazine or pyridazine nucleus. This was substituted with amine, methoxy, methyl groups or halogens in order to obtain long-acting drugs, similarly to those obtained in the field of sulfonamides. The synthesis was accomplished by reaction of sodium p-amino- or p-acetamidobenzensulfinate with the corresponding halodiazine; only the p-aminophenyl 3-aminopyridazin-6-yl sulfone was obtained by acid hydrolysis. The compounds showed good antitubercular activity in vitro.
