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. 22236-08-4, name is 3-(Difluoromethoxy)aniline, A new synthetic method of this compound is introduced below., SDS of cas: 22236-08-4
General procedure: A two neck round bottom flask under argon equipped with acondenser was charged with aldehyde 4 (1.0 equiv.) and 4-chloroaniline 3l (1.1 equiv.) in 2-pentanol [0.3 M] and stirred atreflux for 2 h. The tetronic acid 5 (1.1 equiv.) in 2-pentanol (minimumamount) was then added at reflux. After another 10 min atreflux, the third component aniline 3 (1.0 equiv.) was added neat.The reaction mixture was refluxed for an additional 30 min. Allvolatiles were evaporated under vacuum and the crude product purified by recrystallization in ethanol or by flash chromatographyon silica gel
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.
