Embodiment 1
[0063] Example 1: Synthesis of Compound 1
[0064] 1, synthesis of intermediate 1-1
[0065]
[0066] Intermediates 1-1-2 (22.30 g, 61.4 mm), A (27.90 g, 61.4 mm), tetra (triphenylphosphine) palladium (5 mt), potassium carbonate (5) 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 12 hours under nitrogen. 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 by silica gel column to obtain intermediate 1-1 (30.63 g, yield 72%). LC-MS: M / Z692.26 (M + H) + .
[0067] 2, the synthesis of Compound 1
[0068]
[0069] The intermediate 1-1 (13.86 g, 20 millimorate), B (5.05 g, 21.0 mm), B (5.05 g, 21.0 mm), B (dibenzyl acetone) di palladium (4 marthyme), three t-but Cylin (8%), potassium t-butoxide (3.8 g, 33...
Embodiment 2
[0070] Example 2: Synthesis of Compound 13
[0071] 1, synthesis of intermediate 13-1
[0072]
[0073] Intermediate 1-1-2 (7.24 g, 20 mm), 4-iodine-N, N-diphenylbenzoamine (7.80 grams, 21.0 mm Mochi), 3 (Siya) in a 250 ml of the three flask Benzylcycecetone) Dipalide (4)%), tri-butylphosphine (8% by weight), 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 completion, the reaction solution was cooled to room temperature, extracted with o-chlorophenyl and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and the crystal obtained was crystallized to the compound 13-1 (10.31 g, yield 85%). LC-MS: M / Z605.11 (M + H) + .
[0074] 2, synthesis of intermediate 13-2
[0075]
[0076] Intermediate 13-1 (37.24.24.00 g, 61.4 mm), carbazole-3-boric acid (12.96 g, 61.4 mm), tetra (triphenylphosphine) palladium (5) %), Potass...
Embodiment 3
[0080] Example 3: Synthesis of Compound 26
[0081] The compound 26 is synthesized from the method of Example 1 to obtain compound 26 (10.36 g, yield of 70%). LC-MS: M / Z972.36 (M + H) + .
