[0117] Example 1: Preparation of Compound C-50
[0118]
[0119] Preparation of compound 1-1
[0120] 36g compound A (125.38mmol), 27g 3-bromo-2-chloro-nitrobenzene (113.98mmol), 4g tetrakis (triphenylphosphine) palladium (3.42mmol), 30g sodium carbonate (284.95mmol), 570mL toluene , 140 mL of ethanol, and 140 mL of distilled water were introduced into the reaction vessel, and the mixture was stirred at 120° C. for 3 hours. After the reaction was completed, the mixture was cooled to room temperature, and extracted with ethyl acetate. The extracted organic layer was then dried with magnesium sulfate, and the solvent was removed using a rotary evaporator. After that, the resulting product was purified by column chromatography to obtain 30 g of Compound 1-1 (yield: 66%).
[0121] Preparation of compound 1-2
[0122] 27g of compound 1-1 (68.20mmol), 1.5g of palladium (II) acetate (6.82mmol), 5.0g of tricyclohexylphosphonium tetrafluoroborate (13.64mmol), 66g of cesium...
example 2
[0128] Example 2: Preparation of Compound C-51
[0129]
[0130]5g compound 1-3 (15mmol), 8.6g 2-(4-bromonaphthalen-1-yl)-4,6-diphenyl-1,3,5-triazine (20mmol), 0.4g palladium acetate (II) (2 mmol), 1.2 g of soil inorganic phosphorus (3 mmol), 2.2 g of sodium tert-butoxide (23 mmol), and 76 mL of o-xylene were introduced into a reaction vessel, and the mixture was stirred under reflux for 3 hours. After the reaction was completed, the mixture was washed with distilled water, extracted with ethyl acetate, and the extracted organic layer was dried with magnesium sulfate. The solvent was removed with a rotary evaporator, and the resulting product was purified by column chromatography to obtain 3.3 g of Compound C-51 (yield: 32%).

[0132] Example 3: Preparation of Compound C-49
[0133]
[0134] 6g compound 1-3 (18mmol), 8.5g 2-(4-bromophenyl)-4,6-diphenyl-1,3,5-triazine (22mmol), 0.4g palladium (II) acetate ( 2 mmol), 1.5 g of soil inorganic phosphorus (4 mmol), 2.6 g of sodium tert-butoxide (27 mmol), and 91 mL of o-xylene were introduced into the reaction vessel, and the mixture was stirred under reflux for 2 hours. After the reaction was completed, the mixture was washed with distilled water, extracted with ethyl acetate, and the extracted organic layer was dried with magnesium sulfate. The solvent was removed with a rotary evaporator, and the resulting product was purified by column chromatography to obtain 10 g of compound C-49 (yield: 86%).
