With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.108511-97-3,Isoxazol-4-amine,as a common compound, the synthetic route is as follows.
1-Chloro-4-iodo-2-trifluoromethylbenzene (10 mmol) obtained in Reaction 1.2 was dissolved in 20 ml of toluene.Isoxazole-4-amine (12 mmol) was added sequentially to the system.Palladium acetate (0.5 mmol),2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (12 mmol),3 ml of triethylamine,After stirring for 10 minutes,Add 10 ml of aqueous solution of cesium carbonate (10 mmol),Heat to 50 C for 4 hours.After the reaction was completed, 20 ml of water was added to the system, and the mixture was stirred for 20 minutes, and the organic phase was dried over anhydrous sodium sulfate, concentrated, and purified by flash column chromatography.2.2 g of yellow N-(4-chloro-3-trifluoromethylphenyl)-isoxazole-4-amine powder was obtained in a yield of 84%.
108511-97-3, The synthetic route of 108511-97-3 has been constantly updated, and we look forward to future research findings.
