Zusammenfassung:	FIELD: organic chemistry and technology. SUBSTANCE: invention proposes the synthesis of 3-isopropyl-(1H)-benz-2,1,3-thiadiazinone-4-dioxide-2,2 by intramolecular cyclization of N-(2-carbmethoxyphenyl)-N'-isopropylsulfonyldiamide in anhydrous dimethylsulfoxide and dimethylformamide in the presence of potassium and sodium hydroxide mixture. EFFECT: improved method of synthesis. Предлагается способ получения 3-изопропил(1Н)бенз-2,1,3-тиадиазинон-4- диоксида-2,2 внутримолекулярной циклизацией N-(2-карбметоксифенил)-N'- изопропилсульфонилдиамида в безводных диметилсульфоксиде и диметилформамиде в присутствии смеси едкого кали и едкого натра.
