[0060] Embodiment 1: the synthesis of compound 5

[0061] 1. Synthesis of intermediate 5-2

[0062]

[0063] Add intermediate 5-1 (11.69 g, 20 mmol), bromobenzene (3.30 g, 21.0 mmol), tris(dibenzylideneacetone) dipalladium (4 mole%), tri-tert Butylphosphine (8 mole %), 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 compound 5-2 (8.59 g, yield 65%). LC-MS: M / 600.26 (M+H)+.
