Embodiment 1
[0058] Example 1: Synthesis of Compound 1
[0059] 1, synthesis of intermediate 1-1
[0060]
[0061] Intermediates 2-1-2 (25.37 g, 61.4 mm), 9-phenyl-9H-carbazole-3-boric acid (17.63 g, 61.4 mm), four (triphenyl) Base phosphine) palladium (5%), K2CO3 (17.0 g, 122.8 mm), 1,4-dioxane (200 mL) and water (50 ml). The reaction system was tapered to 80 degrees Celsius, and the reaction was reacted under nitrogen for 12 hours. After the reaction was completed, the reaction solution was cooled to room temperature, extracted with o-dichlorobenzene and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and the crude crystalline was obtained from the silica gel column to obtain intermediate 1-1 (24.74 g, yield of 70%). LC-MS: M / Z575.20 (M + H) + .
[0062] 2, the synthesis of Compound 1
[0063]
[0064] Intermediate 1-1 (11.51 g, 20 milligo), A (5.05 g, 21.0 mm), three (dibenzyl acetone) di palladium (4)%), three t-butarten Cylin (8%), potassium t-buto...
Embodiment 2
[0065] Example 2: Synthesis of Compound 13
[0066] 1, synthesis of intermediate 13-1
[0067]
[0068] Intermediates 2-1-2 (8.27 g, 20 mm), iodobenzene (4.28 g, 21.0 mm), three (dibenzyl acetone) diphodium (4 mismone), Trose-butylphosphine (8%), potassium tert-butoxide (3.8 g, 33.6 mm) and o-xylene (80 mL). The reaction system was tapered to 120 degrees Celsius and the reaction was reacted under nitrogen for 12 hours. After the reaction was completed, the reaction liquid was cold until room temperature, and extracted with o-chlorophenyl and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and a crude crystalline was obtained from the silica gel column to obtain Compound 13-1 (8.12 g, yield 83%). LC-MS: M / Z488.05 (M + H) + .
[0069] 2, synthesis of intermediate 13-2
[0070]
[0071] Intermediate 13-1 (30.05 g, 61.4 mm), carbazole-3-boric acid (12.96 g, 61.4 mm), tetra (triphenylphosphine) palladium (5)%) K2CO3 (17.0 g, 122.8 mm), 1,4-dioxa...
Embodiment 3
[0074] Example 3: Synthesis of Compound 25
[0075] The compound 25 was synthesized from the method of Example 1 to give Compound 25 (10.36 g, yield of 70%). LC-MS: M / Z779.25 (M + H) + .
