| titleOfInvention | PROCEDURE FOR THE PREPARATION OF BENZENOSULFONILUREAS. |
| abstract | Preparation of the sulfonylureas is characterized in that in benzenesulfonylthioureas substituted with **(Formula)** the sulfur atom is replaced by oxygen, and eventually the reaction products are treated with alkaline agents to form salts. The benzenesulfonylcarbamic acid esters or thiol esters mentioned may have an alkyl radical or an aryl radical, or alternatively a betacyclic radical, in the alcoholic component. Since this radical is removed in the reaction, its chemical constitution has no influence on the character of the final product, and can therefore be varied within wide limits. The same applies to the N-R-substituted carbamic acid esters or the corresponding carbamic acid thiol esters. |
