Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 4403-36-5, name is 2-(1,3-Dioxoisoindolin-2-yl)ethanesulfonylchloride, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 2-(1,3-Dioxoisoindolin-2-yl)ethanesulfonylchloride
Bis(4-methoxybenzyl)amine (900 mg) was dissolved in dichloromethane (20 ml) and cooled to 0C. To this solution, triethylamine (1.02 ml) was added and compound 49 (1.05 g) was added in small portions, followed by stirring at room temperature for 3 hours. After addition of water, the reaction mixture was extracted with dichloromethane. The organic layer was washed with brine and dried over magnesium sulfate. After filtration and evaporation of the solvent under reduced pressure, the resulting residue was purified by silica gel column chromatography (developing solvent: ethyl acetate:n-hexane 1:1 to ethyl acetate) to give the desired compound (compound 50) (1.4 g, yield 81%). 1H-NMR (300MHz, CDCl3) delta: 3.24(2H, t, J=6.8Hz), 3.81(6H, s), 4.10-4.14(2H, m), 4.29(4H, s), 6.88(4H, d, J=8.7Hz), 7.23(4H, d, J=8.7Hz), 7.73(2H, dd, J=3.1, 5.3Hz), 7.87(2H, dd, J=3.1, 5.3Hz). Rf value (silica gel plate, developing solvent: ethyl acetate:n-hexane = 1:1): 0.24.
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 4403-36-5.
