As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO97,mainly used in chemical industry, its synthesis route is as follows.,111248-89-6

c. 1-Methyl-1,3-dihydrobenzo[c]isothiazole-2,2-dioxide To a suspension of 1,3-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 muL, 6.62 mmol). The reaction was stirred for 6 h at rt and was then quenched with a sat. NH4Cl solution. The reaction mixture was concentrated and purified by column chromatography (CyHex/acetone) to afford the title compound as a white solid (270 mg, 89%).

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