Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 6292-59-7, name is 4-(tert-Butyl)benzenesulfonamide, A new synthetic method of this compound is introduced below., Formula: C10H15NO2S
Example 3Preparation of 4-tert-butyl-N-[6-chloro-5-(2-methoxyphenoxy)-4-pyrimidinyl]benzene sulfonamide potassium salt using Acetone as a solvent and potassium hydroxide as a base; Acetone (45.0 ml), Potassium hydroxide (1.13 gm) and 4-tert-butylbenzenesulphonamide (1.65 gm) were added at 30 C. and stirred for 5 minutes. 4,6-dichloro-5-(2-methoxyphenoxy)-2,2′-bipyrimidine (3.0 gm) was added at 30 C. and the temperature of the reaction mass was raised to reflux. The reaction mass was stirred at reflux for 6.5 hrs. The reaction mass was cooled gradually to room temperature. Acetone was distilled out from the reaction mass under vacuum below 40 C. Water (30.0 ml) was added to the reaction mass at room temperature and the resulting mass was stirred for 3.0 hrs. The precipitated solid was filtered, washed with water (2¡Á3.0 ml) and dried under vacuum at 55-60 C. for 6.0 hrs to obtain 4.04 gms of 4-tert-butyl-N-[6-chloro-5-(2-methoxyphenoxy)-4-pyrimidinyl]benzene sulfonamide potassium salt. (% Yield: 89%)MS of solid: 564.1 (M+H), 548.1, 514.2, 434.1, 370.0, 352.1, 340.0, 324.1, 249.2, 237.1, 197.6, 182.9
The synthetic route of 6292-59-7 has been constantly updated, and we look forward to future research findings.
