With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.936-16-3,2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide,as a common compound, the synthetic route is as follows.
A mixture of C105 (80 mg, 0.16 mmol), C113 (39.3 mg, 0.232 mmol), cesium carbonate (114 mg, 0.350 mmol), and potassium iodide (28.9 mg, 0.174 mmol) in /V,/V-dimethylformamide (2 mL) was stirred at 80 ¡ãC for 16 hours. The reaction mixture was then diluted with ethyl acetate (30 mL), washed with saturated aqueous sodium chloride solution (3 x 30 mL), dried over sodium sulfate, filtered, and concentrated in vacuo. Preparative thin layer chromatography on silica gel (Eluent: 1 :3 ethyl acetate / petroleum ether) provided the product as a light yellow oil. Yield: 55 mg, 94 muetaiotaomicronIota, 59percent. LCMS m/z 607.0 [M+Na+].
As the paragraph descriping shows that 936-16-3 is playing an increasingly important role.
