Synthetic example 1
[0206] Synthesis Example 1: Synthesis of Compound H01
[0207] (1) Synthesis of intermediate R1
[0208]
[0209] 6.00g (30.6mmol) of S1, 10.70g (67.0mmol) of Br 2 and 128.5 g of acetic acid (AcOH) were put into a 500 mL round bottom flask, and the solution was stirred. After the reaction was completed, the solvent was removed, and then the solid was extracted with dichloromethane and water, and distilled under reduced pressure to obtain a crude product. Then, the crude product was purified through a silica gel column, and the remaining solvent was distilled under reduced pressure again to obtain 17.8 g of intermediate R1.
[0210] (2) Synthesis of intermediate R2
[0211]
[0212] 8.9g (1.53mmol) of intermediate R1, 12.86g (53.6mmol) of 1-iodooctane and 8.46g (61.2mmol) of K 2 CO 3Dissolved in dimethylformamide (DMF), then heated and stirred the solution. After the reaction was completed, the solvent was removed, and then the solid was extracted with dichloromet...

[0216] Synthesis Example 2: Synthesis of Compound H02
[0217] (1) Synthesis of intermediate R3
[0218]
[0219] 8.9 g (1.53 mmol) of intermediate R1, 12.86 g (53.6 mmol) of 1-iodo-2-ethyl-hexane and 8.46 g (61.2 mmol) of K 2 CO 3 Dissolved in dimethylformamide (DMF), then heated and stirred the solution. After the reaction was completed, the solvent was removed, and then the solid was extracted with dichloromethane and water under reduced pressure to obtain a crude product. Then, the crude product was purified through a silica gel column, and the remaining solvent was distilled under reduced pressure again to obtain 12.5 g of intermediate R3.
[0220] (2) Synthesis of compound H02
[0221]
[0222] Dissolve 4.0g (4.4mmol) of intermediate R3, 0.74g (21.54mmol) of carbazole, 0.28g of bis (tri-tert-butylphosphine) palladium (0) (Pd(P(t) in 70mL of toluene -Bu) 3 ) 2 ) and 4 g of sodium tert-butoxide (t-BuONa) were put into a 100 mL round bottom flask, and the sol...

[0223] Synthesis Example 3: Synthesis of Compound H03
[0224] (1) Synthesis of intermediate R4
[0225]
[0226] 30.00 g (22.70 mmol) of S3, 24.83 g (68.10 mmol) of concentrated HCl and 450 g of AcOH were placed in a 500 mL round bottom flask, and the solution was stirred. After the reaction was completed, the resulting solid was filtered with excess water to obtain 40 g of intermediate R4.
[0227] (2) Synthesis of intermediate R5
[0228]
[0229] 10.0g (2.92mmol) of intermediate R4, 11.97g (7.3mmol) of 1-bromohexane, 1.63g of KOH and 0.5g of KI were dissolved in dimethylsulfoxide (DMSO), and the solution was heated at room temperature Set aside overnight. After the reaction was completed, the solvent was removed, and then the solid was extracted with dichloromethane and water, and distilled under reduced pressure to obtain a crude product. Then, the crude product was purified through a silica gel column, and the remaining solvent was distilled under reduced pre...
