Embodiment 1
[0041] Example 1: Synthesis of Intermediate N-1
[0042]
[0043] Under a nitrogen atmosphere, add 0.02mol of raw material A-1 to a 500ml three-necked flask, add a mixed solvent (120ml toluene, 36ml H 2 O) Dissolve it, pass nitrogen and stir for 1 hour, then slowly add 0.011mol raw material B-2, 0.04molK 2 CO 3 , 0.002mol Pd (PPh 3 ) 4 , heated to 90° C., reacted for 8 hours, and observed the reaction by thin layer chromatography (TLC) until the reaction was complete. After naturally cooling to room temperature, water was added to the reaction system for extraction, the liquid was separated, and the organic phase was rotary-evaporated under reduced pressure until there was no fraction. The obtained material was purified by silica gel column to obtain Intermediate N-1 with a purity of 99.7% and a yield of 76.8%. Elemental analysis structure (molecular formula C 42 H 31 ClN 2 ): Theoretical: C, 84.19; H, 5.22; Cl, 5.92; N, 4.68; found: C, 84.11; H, 5.24; Cl, 5.93;...

The obtained material was purified by silica gel column to obtain intermediate N-2 with a purity of 99.7% and a yield of 75.6%. Elemental analysis structure (molecular formula C 42 H 31 ClN 2 ): Theoretical: C, 84.19; H, 5.22; Cl, 5.92; N, 4.68; found: C, 84.09; H, 5.24; Cl, 5.93;...
Embodiment 3
[0047] Example 3: Synthesis of Intermediate N-3
[0048]
[0049]Under a nitrogen atmosphere, add 0.02mol of raw material C-1 to a 500ml three-necked flask, add a mixed solvent (120ml toluene, 36ml H 2 O) Dissolve it, pass nitrogen and stir for 1 hour, then slowly add 0.011mol raw material B-4, 0.04molK 2 CO 3 , 0.002mol Pd (PPh 3 ) 4 , heated to 90° C., reacted for 8 hours, and observed the reaction by thin layer chromatography (TLC) until the reaction was complete. After naturally cooling to room temperature, water was added to the reaction system for extraction, the liquid was separated, and the organic phase was rotary-evaporated under reduced pressure until there was no fraction. The obtained material was purified by silica gel column to obtain intermediate N-3 with a purity of 99.6% and a yield of 72.9%. Elemental analysis structure (molecular formula C 42 H 27 ClN 2 ): Theoretical: C, 84.76; H, 4.57; Cl, 5.96; N, 4.71; found: C, 84.69; H, 4.59; Cl, 5.97; ...
