With the rapid development of chemical substances, we look forward to future research findings about 936-16-3

The isothiazole compound, cas is 936-16-3 name is 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide, mainly used in chemical industry, its synthesis route is as follows.,936-16-3

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

With the rapid development of chemical substances, we look forward to future research findings about 936-16-3
