Synthetic example 1
[0075] Synthesis Example 1: Synthesis of Compound P1
[0076]
[0077] Add 8.79g (35mmol) of isopropylcarbazole into a 250ml three-neck flask, add 100ml of N,N-dimethylformamide as a reaction solvent, and stir on a magnetic stirrer for 10min under ice-bath conditions. 0.72g (30mmol) NaH was added to the reaction flask in batches, and the stirring was continued for 1h. Dissolve 2.07g (10mmol) of 2,4,6-trichloro-5-cyanopyrimidine in 40ml of N,N-dimethylformamide solution and add it dropwise to the reaction system. Under reaction 24h. After the reaction, the reaction solution was poured into 200ml concentration of 10% dilute hydrochloric acid to quench, after vacuum filtration, washed with water, dried, the crude product obtained was washed with petroleum ether and dichloromethane (PE:DCM=10: 1) Pass the column as the mobile phase. 5.56 g of white solid powder was obtained with a yield of 65.2%. (1HNMR(δ,CDCl3):7.40(6H,s),7.28(6H,s),6.71-6.68(6H,d),3.08-3.01(6H,m),1.19-1.1...

[0079]
[0080] Add 8.79g (35mmol) of isopropylcarbazole into a 250ml three-neck flask, add 100ml of N,N-dimethylformamide as a reaction solvent, and stir on a magnetic stirrer for 10min under ice-bath conditions. 0.72g (30mmol) NaH was added to the reaction flask in batches, and the stirring was continued for 1h. Dissolve 2.83g (10mmol) of 2,4,6-trichloro-5-cyanophenylpyrimidine in 40ml of N,N-dimethylformamide solution and add it dropwise to the reaction system. Reaction at room temperature for 24h. After the reaction, the reaction solution was poured into 200ml concentration of 10% dilute hydrochloric acid to quench, after vacuum filtration, washed with water, dried, the crude product obtained was washed with petroleum ether and dichloromethane (PE:DCM=10: 1) Pass the column as the mobile phase. 4.99 g of white solid powder was obtained with a yield of 53.7%.

Synthetic example 3
[0082] Synthesis Example 3: Synthesis of Compound P5
[0083]
[0084] Under nitrogen protection, 6.28g (25mmol) isopropylcarbazole, 2.83g (10mmol) 2,4,6-trichloro-5-cyanopyrimidine, 1.92g (20mmol) NaOBu-t, 1.92g (0.2 mmol)(t-Bu) 3 HBF 4 , 0.09g (0.1mmol) Pd 2 (dba) 3 Add it into a 250ml three-neck flask, add 100ml of toluene as a reaction solvent, heat up to reflux temperature, and stir overnight on a magnetic stirrer. After the reaction, the reaction solution was spin-dried, and the obtained crude product was passed through the column with petroleum ether and dichloromethane (PE:DCM=5:1) as the mobile phase. Intermediate 1 was obtained as white solid powder, weighing 4.70 g, and the yield was 73.7%.
[0085] 1.56g (7.5mmol) 9,9-Dimethylacridine Add to a 250ml three-neck flask, add 50ml of N,N-dimethylformamide as a reaction solvent, and stir on a magnetic stirrer for 10min under ice-bath conditions. 0.36g (15mmol) NaH was added to the reaction flask in batches, an...
