Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 22236-10-8, name is 4-(Difluoromethoxy)aniline, A new synthetic method of this compound is introduced below., 22236-10-8
Into a 250-mL round-bottom flask purged with and maintained under nitrogen was placed 4- (difluoromethoxy)benzenamine (10 g, 62.8 mmol), ACN (100 mL), and BS (5.59 g, 31.4 mmol). The resulting solution was stirred for 1 h 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 :20 to 1 : 10). This resulted in 7.9 g (53%) of the title compound as red oil. MS-ESI: 238.0/240.0 (M+l).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
