Abstract
Improvement in the process for the preparation of a sulphamidomethoxypyridazine sulfamide characterized by the fact that chlorodilfamidopyridazine is prepared by condensation of dichloropyridazine with p-aminobenzenesulfamide by means of heat in an inert diluent such as high boiling point vaseline oil in the presence of potassium carbonate and copper powder as a stabilizer, then proceeding to the appropriate methoxylation of chlorosulfamidopyridine by any method of general chemistry known or not.
