Embodiment 1
[0112] Synthesis Example 1: Synthesis of Compound 1
[0113]
[0114] Add 100 mmol of 2-bromo-1-methoxynaphthalene, 120 mmol of n-butyllithium, 130 mmol of tributyl borate, and 1200 ml of THF into the reaction flask. React at -85°C for 12h. After the reaction was completed, the reaction was stopped, and the reactant was returned to room temperature, added with water, filtered, and washed with water. The obtained solid was recrystallized and purified with toluene to obtain a white powder M1.
[0115] Add 100mmol of M1, 100mmol of 1-bromo-4-chloro-2-fluorobenzene, 27.6g of potassium carbonate (200mmol), 2.1L of toluene, 700ml of ethanol and 700ml of water in the reaction flask, and add 0.6mol% Pd(0). The reaction was refluxed at 95°C for 12h. After the reaction was completed, the reaction was stopped, and the reactant was returned to room temperature, added with water, filtered, and washed with water. The obtained solid was recrystallized and purified with toluene to obtai...
Embodiment 2
[0123] Synthesis Example 2: Synthesis of Compound 15
[0124]
[0125] In the reaction flask, add 100mmol of M5 (the synthesis method is the same as that of M5 in Example 1), 100mmol of 3-chlorodibenzo[b, d]furan, 200mmol of sodium tert-butoxide, 0.6mol% of Pd2(dba )3 and 2.4mol% of Xphos and added 1.5L of toluene. Reflux reaction at 90°C for 12h. After the reaction was completed, the reaction was stopped, and the reactant was returned to room temperature, added with water, filtered, washed with water, and the obtained solid was recrystallized and purified with toluene to obtain a white powder M6. Wherein, the addition amount of Pd2(dba)3 is 0.6 mol% of M5, and the addition amount of Xphos is 2.4 mol% of M5.
[0126] Add 100mmol of 2-bromonaphthalene, 100mmol of 4-chlorophenylboronic acid pinacol ester, 27.6g of potassium carbonate (200mmol), 2.5L of toluene, 800ml of ethanol and 800ml of water in the reaction flask, and add 0.6mol% Pd132. The reaction was refluxed at 9...

The reaction was refluxed at 95°C for 12h. After the reaction was completed, the reaction was stopped, and the reactant was returned to room temperature, added with water, filtered, washed with water, and the obtained solid was recrystallized and purified with toluene to obtain a white powder M6. Wherein, the addition amount of Pd132 is 0.6 mol% of 3-chlorodibenzo[b,d]furan.
[0133] In the reaction flask, add 100mmol of M5 (the synthesis method is the same as that of M5 in Example 1), 100mmol of M6, 200mmol of sodium tert-butoxide, 0.6mol% of Pd2(dba)3 and 2.4mol% of Xphos and add 1.5 L of toluene. Reflux reaction at 90°C for 12h. After the reaction was completed, the reaction was sto...
