With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.76982-23-5,5-Bromoquinoxaline,as a common compound, the synthetic route is as follows.,76982-23-5
Under a nitrogen atmosphere, the compound of formula C (0.658 g, 3.30 mmol), The compound of formula D (1.518 g, 7.26 mmol), Sodium tert-butoxide (0.952 g, 9.90 mmol), Bis (dibenzylideneacetone) palladium (0) (0.114 g), bis (diphenylphosphino) – 1,1′-binaphthalene (0) 100 mL of toluene was added to [(¡À) -2,2′-Bis (diphenylphosphino) -1,1′-binaphthalene] (0.185 g, 0.297 mmol) and refluxed for 12 hours. After the temperature was lowered to room temperature, the mixture was washed with water, the residue was removed with MgSO 4, hydrazine monohydrate was added thereto, and the mixture was stirred at room temperature for 30 minutes. Precipitated in hexane, filtered off the solid, and dried under vacuum to obtain the compound 2
As the paragraph descriping shows that 76982-23-5 is playing an increasingly important role.
