Abstract: A process for producing salts of 3-isopropyl-2,1,3-benzothiadiazine-4-on-2,2-dioxide of general formula (I) (R1-R4 = H, lower alkyl, lower hydroxyalkyl) by reacting bentazone (IIa) in an organic solvent with an amine (IIIa), reacting bentazone (IIa) in an organic solvent virtually immiscible with water with an amine (IIIa) or an ammonium salt (IIIb) and taking salt (I) up in water or reacting bentazone (IIa) with an ammonium salt (IIIb) or sodium bentazone (IIb) with an ammonium salt (IIIc) in water.

Abstract: Prepn. of 3-isopropyl-2,1,3-benzothiadiazin-4-one-2,2-dioxide salts (A) of formula (I; Q = NHR1R2R3) comprises reacting 3-isopropyl-2,1,3-benzothiadiazin-4-one-2,2-dioxide of formula (IIa) with an amine of formula NR1R2R3 (IIIa) in an organic solvent. R1-R3 = H or lower (hydroxy)alkyl. Also claimed is the prepn. of salts (B) of formula (I; Q = NR1R2R3R4) by reacting (IIa) with (IIIa) or an ammonium salt of formula (NR1R2R3R4ÜnX (IIIb) in a solvent that is practically immiscible with water, opt. in the presence of water; and extracting (I) with water. R4 = as R1; X = the anion of an acid with pKa greater than 4 or esp. the OH ion; n = the charge on X. Also claimed is the prepn. of (B) by reacting (IIa) with (IIIb), or (I; Q = Na) with an ammonium salt of formula (NR1R2R3R4ÜmY (IIIc), in water. Y = the anion of an acid; m = the charge on Y.
