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. 175278-09-8, name is 4-Bromo-2-(trifluoromethoxy)aniline, A new synthetic method of this compound is introduced below., Recommanded Product: 175278-09-8
EXAMPLE 647-(2,6-dichlorobenzyl)-5-{ [4-^iperazin- l -yl)-2-(trifluoromethoxy)phenyl]amino}pyrido[3,4- d]pyridazin-4-ol EXAMPLE 64A /V,N-dibenzyl-4-bromo-2-(trifluoromethoxy)aniline To a mixture of 4-bromo-2-(trifluoromethoxy)aniline (5 g. 19.53 mmol) and potassium carbonate (8.09 g, 58.89 mmol) in acetonitrile (200 mL) was added (bromomethyl)benzene (6.96 mL, 58.59 mmol) and the mixture was refluxed for 20 hours. The mixture was filtered and the filtrate was concentrated. The residue was purified by flash chromatography on silica gel (200-300 mesh) eluting with 5/1 petroleum ether/ethyl acetate to give the title compound. MS : 436 (M + H+).
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.
