| titleOfInvention | METHOD FOR THE PRODUCTION OF 1, 1 - DIOXIDES OF SULFAMYLO - 3,4 - DIHYDRO - 1, 2, 4 - BENZOTHIADIAZINE. |
| abstract | Method for the preparation of 1,4-dihydro-1,2,4-benzothiadiazine 1,1-dioxide of general formula:n[*]nof the N-acyl derivatives and salts of these compounds, wherein R1, R3, R5 and R6 are substituted for hydrogen or alkyl residues, R2 is the hydrogen of an unsubstituted or substituted hydrocarbon residue or heterocyclic residue, R4 hydrocarbons, esterified or etherified hydroxyl groups or halides and, in this case, R2, R3 and R6 mean hydrogen and R4chlorine, R1 represents an alkyl- or acyl residue, characterized in that it contains a type of sulphate;n[*]nor in its salts, wherein R4, R5 and R6 have the above meaning, and R1 and R3 mean hydrogen or alkyl, reacting with an aldehyde of formula R2CHO, wherein R2 has the above meaning, or Benzothiadiazine 1,1-dioxide of general formula:n[*]nand the N-acyl compounds thereof, wherein R1, R2, R3, R4, R5 and R6 have the above importance, reduce the CN-double bond and the resulting compounds are treated with substituted nitrogen atoms, if desired, at any time. R1, R2, R3, R5 and R6 denote hydrogen and R4 denotes the chlorine atom, treated with alkyl residues and / or acylating agents, and / or, if desired, converted salts to the free compounds or free compounds. compounds are converted to their salts. |
