Embodiment 1
[0073] Embodiment 1: the synthesis of compound 1
[0074]
[0075] In a 250mL three-neck flask, blow nitrogen gas, add 0.02mol raw material A-1 and dissolve in 100mL tetrahydrofuran (THF), then add 0.024mol raw material B, 0.0002mol (1,1'-bis(diphenylphosphine) Iron) dichloropalladium (II) and 0.05mol potassium acetate are added, the mixture is stirred, and the mixed solution of the above reactants is heated to reflux at a reaction temperature of 80°C for 5 hours; after the reaction is completed, cool and add 100mL of water, and filter the mixture and dried in a vacuum oven. The obtained residue was separated and purified by silica gel column to obtain intermediate M-1.
[0076] In a 250mL three-neck flask, blow nitrogen gas, add 0.02mol raw material C, 150mL DMF, 0.072mol intermediate M-1 and 0.0006mol palladium acetate, stir, and then add 0.09mol K 3 PO 4 The aqueous solution was heated to 150°C, refluxed for 10 hours, sampled and plated, and the reaction was complete....
