Embodiment 1
[0063] A method for preparing an organic electroluminescent compound, using the above synthetic route, comprising the following steps:
[0064] Add raw material 2 (44.6mmol) and 100mlTHF into the reaction vessel, ventilate 3 times and cool down to -78°C, add 2.5mol / L n-BuLi (17.8ml, 44.6mmol) under nitrogen atmosphere and stir for 2h, add raw material 1 ( 37mmol) to 25°C, stirred for 10h, and the reaction was completed. Distilled water was then added to the reaction solution to quench the reaction, and the reaction solution was extracted with DCM. Then use magnesium sulfate to dry the extracted organic layer, and use a rotary evaporator to remove the solvent, and use DCM and PE (volume ratio 1:6) to separate out the solid to obtain intermediate 1 (14.0 g, yield 74.5%, MW: 508.11) .
[0065] Add intermediate 1 (26.2mmol) to the reaction flask, add 240ml of glacial acetic acid, raise the temperature to 80°C, add 12ml of concentrated sulfuric acid dropwise, the reaction is comp...
Embodiment 2
[0069] A method for preparing an organic electroluminescent compound, using the above synthetic route, comprising the following steps:
[0070] Add raw material 2 (44.6mmol) and 100mlTHF into the reaction vessel, ventilate 3 times and cool down to -78°C, add 2.5mol / L n-BuLi (17.8ml, 44.6mmol) under nitrogen atmosphere and stir for 2h, add raw material 1 ( 37mmol) to 25°C, stirred for 10h, and the reaction was completed. Distilled water was then added to the reaction solution to quench the reaction, and the reaction solution was extracted with DCM. The extracted organic layer was then dried using magnesium sulfate, and the solvent was removed using a rotary evaporator, and the solid was precipitated with DCM and PE (1:6) to obtain Intermediate 1 (12.6 g, yield 74.4%, MW: 457.90).
[0071] Add intermediate 1 (26.2mmol) to the reaction flask, add 240ml of glacial acetic acid, raise the temperature to 80°C, add 12ml of concentrated sulfuric acid dropwise, the reaction is complete...

Distilled water was then added to the reaction solution to quench the reaction, and the reaction solution was extracted with DCM. Then use magnesium sulfate to dry the extracted organic layer, and use a rotary evaporator to remove the solvent, and use DCM and PE (volume ratio 1:6) to separate out the solid to obtain intermediate 1 (14.1g, yield 74.1%, MW:514.10) .
[0077] Add intermediate 1 (26.2mmol) to the reaction flask, add 240ml of glacial acetic acid, raise the temperature to 80°C, add 12ml of concentrated sulfuric acid dropwise, the reaction is comple...
