[0096] The synthesis of embodiment 1 compound 1
[0097]
[0098] The concrete synthetic route of this compound is provided now:
[0099]
[0100] In a 250ml four-neck flask, under a nitrogen atmosphere, add 0.01mol 4-(4-bromophenyl)-2,6-bis-(4-tert-butylphenyl)-pyrimidine, 0.015molN,N, N',N'-Tetra-p-benzyl-9H-carbazole-3,6-diamine, 0.03mol sodium tert-butoxide, 1×10 -4 mol Pd 2 (dba) 3 , 1×10 -4 mol of tri-tert-butylphosphine, 150ml of toluene, heated to reflux for 24 hours, sampling plate, showing no bromide remaining, the reaction was complete; naturally cooled to room temperature, filtered, and the filtrate was subjected to vacuum rotary evaporation (-0.09MPa, 85°C), After passing through a neutral silica gel column, the target product was obtained with a purity of 99.80% and a yield of 62.20%.
