• Synthesis

  4-(3-Amino-1,2,4-triazin-6-yl)-2-fluorobenzonitrile could be synthesize from the reaction of 6-bromo-1,2,4-triazin-3-amine with 2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile. A solution concluding these two compounds in 1,4-dioxane (1200 mL) was stirred before K2CO3 was added. The reaction mixture was degassed by bubbling with nitrogen before 1,1'-bis(diphenyl phosphine)ferrocene dichloropalladium(II) complex with dichloromethane (1:1) (Pd(dppf)2Cl2 was added. The resulting reaction mixture was degassed by bubbling with nitrogen and then heated at 86° C. After the reaction mixture was cooled to 0-5° C. 1,4-Dioxane was added before aqueous hydrochloric acid solution was added dropwise to adjust pH to 0.40-0.93. The mixture was stirred at for 30 min and filtered. The solid collected was stirred with 1,4-dioxane, and HCl added. Finally, after purification, product 4-(3-Amino-1,2,4-triazin-6-yl)-2-fluorobenzonitrile was obtained.
