936-16-3,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.
Step 1. To a mixture of 6-methyl-2,4-dichloropyrimidine (162 mg, 0.994 mmol) and 1 (185 mg, 1.1 mmol) in anhydrous CH3CN (4 mL) was added K2CO3 (274 mg, 2 mmol), the mixture was stirred at 80¡ãC for 3 hrs. Concentration under reduced pressure resulted in 11 (130 mg), which was submitted to the next step without further purification.
936-16-3 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide 13638, aisothiazole compound, is more and more widely used in various fields.
