Abstract
Process for obtaining a new heterocyclic compound, especially 6-chloro-7-sulfamyl-3,4-dihydro-l, 2,4-benzothiadiazine 1,1-dioxide of the formula ** (See formula) ** and its salts, characterized in that 5-chloro-2,4-disulfamyl-aniline or a salt thereof is reacted with formaldehyde or with a reactable functional derivative of an acetic acid of the formula HalCH2COOH where Hal is by a halogen atom or in 6-oloro-7-sulfamyl-1,1,1-dioxide, 2,4-benzothiadiazine the double C = N bond is reduced and, if desired, the salts obtained are they transform into the free compound or the free compound, into their salts.
