Embodiment 1
[0027] A compound containing triazine group, its preparation method is as follows:
[0028] 1) Add compound 1 (2eq), cyanuric chloride (1eq), tetrakistriphenylphosphine palladium catalyst (0.05eq) and cuprous iodide (0.1eq) into the reaction flask, pump out nitrogen, and inject oxygen-free carbonic acid Potassium aqueous solution (2mol / L) and appropriate amount of toluene were reacted overnight at 80°C, the product was washed with water and extracted three times with dichloromethane, the organic phases were combined, dried with anhydrous sodium sulfate, and the solvent was removed by rotary evaporation, and dichloromethane was used as eluent Silica gel column chromatography was carried out to obtain product 2 with a yield of 65%;
[0029] The reaction formula is as follows:
[0030]
[0031] 2) Compound 2 was dissolved in DMF, 2 times the molar amount of reduced copper powder was added, heated to reflux overnight, and the final product 3 was obtained by silica gel column c...
