Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide, 936-16-3

936-16-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide, cas is 936-16-3,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.

Intermediate 30Ethyl 1 -[4-(1 ,1 -dioxido-1 ,2-benzisothiazol-2(3H)-yl)phenyl]-3-[[(frapis-4- methylcyclohexyl)carbonyl](1-methylethyl)amino]-1H-pyrazole-4-carboxylateA solution of Intermediate 5 (108 mg), 2,3-dihydro-1 ,2-benzisothiazole 1 ,1 -dioxide (35 mg), copper (I) iodide (4 mg), potassium carbonate (58 mg) and (IR^RJ-lambda/./V-dimethyl-i ^- cyclohexanediamine (12 mg) in DMF (4 mL) was heated in a microwave at 100¡ã C, 300 W for 1 h and then evaporated to dryness. The residue was dissolved in ethyl acetate and washed sequentially with aqueous sodium bicarbonate solution, water and 2M HCI, dried using a EPO hydrophobic frit and evaporated to dryness. The crude product was then purified by MDAP HPLC to give the title compound. MS calcd for (C30H36N4O5 + H)+: 565 MS found (electrospray): (M+H)+ = 565
