In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 367-22-6 as follows. Recommanded Product: 4-Chloro-3-fluoroaniline
Into a 500-mL round-bottom flask was placed 4-chloro-3-fluoroaniline (5.08 g, 34.9 mmol), ACN (200 mL), and NBS (18.69 g, 105.0 mmol). The resulting solution was stirred for 12 h at RT and then was concentrated under vacuum. The residue was applied onto a silica gel column and eluted with a gradient of ethyl acetate/petroleum ether (1 :200 to 1 : 100). This resulted in 9.7 g (92%) of the title compound as a light yellow solid. MS-ESI: 303.8/305.8/301.8 (M+l).
According to the analysis of related databases, 367-22-6, the application of this compound in the production field has become more and more popular.
