Abstract: A process for the preparation of N-phenyl(pyridyl)sulfonyldiamides by reacting a 2-aminobenzoic acid (nicotinic acid) derivative with sulfur trioxide, chlorosulfonic acid or an adduct of sulfur trioxide with a tertiary amine in the presence of a diluent and of a tertiary amine, and reacting the resulting sulfamate with a primary amine and a phosphorus halide, or by reacting a 2-aminobenzoic acid (nicotinic acid) derivatives with an N-alkyl(cycloalkyl)sulfamic acid or a salt of this acid in the presence of a diluent and of a phosphorus halide.

Abstract: New and valuable process for the manufacture of 2,1,3-thiadiazin-4-one-2,2-dioxide derivatives by reaction of anthranilic acid amide or aminopyridine carboxamide derivatives with sulfur trioxide derivatives to give the sulfamic acid salts, followed by cyclization of these salts.
