Abstract: Production of 3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one-2,2-dioxide (I) from anthranilic acid isopropylamide (II) in a single step is claimed. Production of the benzothiadiazinone-dioxide of formula (I) comprises reacting anthranilic acid isopropylamide of formula (II) simultaneously with (a) sulphur trioxide or chlorosulphonic acid in the presence of an organic base, or with adducts of SO3 and organic base; and (b) phosphorus oxychloride. The reaction is carried out at from 50 deg C to the reflux temperature, and the (I) produced is optionally converted to its salt.

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.
