[0024] Step ①:
[0025]
[0026]
[0027] Under a nitrogen atmosphere, weigh 5 mmol of raw material A and dissolve it in 80 mL of tetrahydrofuran, then add 5 mmol of raw material B and 0.1 mmol of tetrakis(triphenylphosphine) palladium, stir the mixture, then add 40 mL of an aqueous solution containing 10 mmol of potassium carbonate, The mixed solution of the above reactants is heated to reflux at a reaction temperature of 70-90°C for 5-20 hours. After the reaction, cooling and adding water, the mixture was extracted with dichloromethane, the extract was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure, the obtained residue was purified by silica gel column to obtain Intermediate A;
[0028] Step ②:
[0029]
[0030] Under a nitrogen atmosphere, weigh 5 mmol of intermediate A and dissolve it in 80 mL of tetrahydrofuran, then add 5 mmol of raw material C and 0.2 mmol of tetrakis(triphenylphosphine) palladium, stir the mixture, and ...
