preparation Embodiment 1
[0124] Preparation Example 1 Synthesis of H12:
[0125]
[0126] Under nitrogen protection, weigh compound S2 (1.5mmol), S7 (3.2mmol), [Pd 2 (dba) 3 ]·CHCl 3(0.1mmol) and HP(tBu) 3 ·BF 4 (0.2mmol), was added to a 100mL two-necked flask. Inject 30 mL of toluene into the two-necked flask (pass N in advance 2 15min to remove oxygen), and then add 2.5mL concentration of 1M K 2 CO 3 Aqueous solution (pass N in advance 2 15min to remove oxygen), and stirred overnight at room temperature. After the reaction was completed, 20 mL of deionized water was added, followed by a few drops of 2M HCl. Extract with dichloromethane, collect the organic phase, and wash with anhydrous Na 2 SO 4 Dry processing. The dried solution was filtered, and the solvent was removed by a rotary evaporator to obtain a crude product. The crude product was purified by silica gel column chromatography, and the final purification afforded solid H12 (1.16 mmol, 71%).

[0129] Preparation Example 2 Synthesis of H33:
[0130]
[0131] Under nitrogen protection, weigh compound S6 (1.95mmol), S8 (4.16mmol), [Pd 2 (dba) 3 ]·CHCl 3 (0.12mmol) and HP(tBu) 3 ·BF 4 (0.24mmol), was added to a 250mL two-necked flask. Inject 50mL of toluene into the two-necked flask (pass N in advance 2 15min to remove oxygen), and then add 3.5mL of 1M K2CO3 aqueous solution dropwise (pass N 2 15min to remove oxygen), and stirred overnight at room temperature. After the reaction was completed, 25 mL of deionized water was added, followed by a few drops of 2M HCl. Extract with dichloromethane, collect the organic phase, and wash with anhydrous Na 2 SO 4 Dry processing. The dried solution was filtered, and the solvent was removed by a rotary evaporator to obtain a crude product. The crude product was purified by silica gel column chromatography, and the final purification afforded solid H33 (1.32 mmol, 68%).
