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. 20780-72-7, name is 4-Bromoisatin, This compound has unique chemical properties. The synthetic route is as follows., name: 4-Bromoisatin
Into a 250-mL round-bottom flask, was placed 4-bromo-2,3-dihydro-1H-indole-2,3- dione (2.25 g, 9.95 mmol, 1.00 equiv), N,N-dimethylformamide (50 mL), sodium hydride (480 mg, 12.00 mmol, 2.00 equiv), and iodomethane (1.7 g, 11.98 mmol, 1.20 equiv). The resulting solution was stirred for 1 h at room temperature in a water/ice bath. The resulting solution was diluted with 800 mL of EA then washed with 4×50 mL of brine. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 2 g (84percent) of 4-bromo-1-methyl-2,3-dihydro-1H-indole-2,3-dione as a red solid
