As a common heterocyclic compound, it belongs to Benzisoxazole compound, name is 5-Chloro-3-phenylbenzo[c]isoxazole, and cas is 719-64-2, its synthesis route is as follows.
The preparation method is as follows: 5-chloro-3-phenyl 2,1-benzisoxazole (commercially available) (0.3 mmol, 68.7 mg), phenylacetaldehyde (0.6 mmol, 72.0 mg), copper powder (0.06) Methanol, 3.8 mg) and silver triflate (0.03 mmol, 8.0 mg) were added to a 25 ml Schlenk tube, and the reaction tube was replaced with oxygen three times under reduced pressure.Hexafluoroisopropanol (2 ml) was added and stirred at 110 C for 30 hours.After completion of the reaction, a column chromatography of silica gel of 100-200 mesh was added, and the solvent was evaporated under reduced pressure. The crude product was subjected to silica gel column chromatography, eluting with petroleum ether and ethyl acetate ( petroleum ether: ethyl acetate = 20:1) The liquid was eluted, and the elution was carried out by TLC elution. The eluate containing the desired product was collected, and the desired product eluent was combined and evaporated to give the quinoline compound of the formula i above, yield 69%. This material is a red solid.
With the complex challenges of chemical substances, we look forward to future research findings about 719-64-2,belong Benzisoxazole compound
