Name is 1,3-Dihydrobenzo[c]isothiazole 2,2-dioxide, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 111248-89-6, its synthesis route is as follows.,111248-89-6

4c. 1-Methyl-i ,3-dihydrobenzo[c]isothiazole-2 ,2-dioxide To a suspension of I ,3-dihydrobenzo[c]isothiazole-2,2-dioxide (280 mg,1.655 mmol) and potassium carbonate (229 mg, 1.66 mmol) in DMF (5 mL) was added iodomethane (414 pL, 6.62 mmol). The reaction was stirred for 6 hr at RT andwas then quenched with a sat. NH4CI solution. The reaction mixture was concentratedand purified by column chromatography (CyHex/acetone) to afford the title compound asa white solid (270 mg, 89%). 1H NMR (500 MHz, CDCI3) ppm = 7.37-7.32 (m, 1H), 7.27-7.24 (m, 1H), 7.02 (td, J=7.6, 1.0, IH), 6.73 (d, J8.0, IH), 4.34 (s, 2H), 3.14 (s, 3H); Rt= 2.07 mm (H PLC method F).

With the complex challenges of chemical substances, we look forward to future research findings about 1,3-Dihydrobenzo[c]isothiazole 2,2-dioxide
