Embodiment 1
[0044] Embodiment 1: the synthesis of compound 1-1
[0045] 1. Synthesis of intermediate Sub-1
[0046]
[0047] In the 500mL reaction flask, add intermediate phenylboronic acid (7.49g, 61.4mmol), 2,4-dibromothiazole (17.68g, 61.4mmol), tetrakis (triphenylphosphine) palladium (5mol%), K2CO3 (17.0g , 122.8mmol), 1,4-dioxane (200mL) and water (50mL). The temperature of the reaction system was raised to 80° C., and reacted for 12 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, and extracted with o-dichlorobenzene and water. The organic layer was dried with anhydrous magnesium sulfate, concentrated and recrystallized, and the crude product obtained was passed through a silica gel column to obtain the intermediate Sub-1 (13.13 g, yield 75%). LC-MS: M / Z 283.99 (M+).
[0048] 2. Synthesis of intermediate Sub-4
[0049]
[0050] In a 250ml three-necked flask, add intermediate Sub-3 (3.46g, 10mmo...
Embodiment 2
[0054] Embodiment 2: the synthesis of compound 1-5
[0055] 1. Synthesis of intermediate Sub-5
[0056]
[0057] In a 250ml three-necked flask, add intermediate 2,4-dibromobenzo[4,5]thieno[3,2-d]pyrimidine (3.85g, 11.2mmol), intermediate carbazole (3.0g, 12.3mmol) , tris(dibenzylideneacetone)dipalladium (4 mol%), tri-tert-butylphosphine (8 mol%), potassium tert-butoxide (3.8 g, 33.6 mmol) and o-xylene (80 mL). The temperature of the reaction system was raised to 120° C. and reacted for 12 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, and extracted with o-dichlorobenzene and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and recrystallized to obtain the crude product through a silica gel column to obtain Sub-5 (3.86 g, yield 80%). LC-MS: M / Z 430.32 (M+).
[0058] 2. Synthesis of compound 1-5
[0059]
[0060] Compound 1-5 was synthesized with referenc...
Embodiment 3
[0061] Embodiment 3: the synthesis of compound 1-10
[0062]
[0063] Compound 1-10 was synthesized with reference to the method of Example 1, and other steps were referred to the synthesis of compound 1-1 to obtain compound 1-10 (4.45 g, yield 60%). LC-MS: M / Z 742.31 (M+).
