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. 317-20-4, name is 7-Fluoroisatin, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 317-20-4
To a stirred solution of 7-fluoroindoline-2,3-dione (500 mg, 3.03 mmol) in DMF (5 mL) were successively added K2C03 (502 mg, 3.63 mmol) and methyl iodide (0.199 mL, 3.18 mmol). The resulting mixture was stirred at RT for 1 hr. The mixture was quenched with water, diluted with EtOAc and saturated aqueous NaHC03 solution and both phases were separated. The aqueous layer was extracted with EtOAc. The combined organic layers were washed with brine, dried over anhydrous MgS04, filtered and concentrated under reduced pressure to afford the title product (497 mg, 2.219 mmol, 73.3% yield) as yellow solid. Rt = 0.69 min (UPLC-MS); ESI-MS = 179.9 [M+1]+ (UPLC-MS).
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 317-20-4.
