Embodiment 1

[0048]Embodiment 1: the synthesis of compound 295

[0049] (1) Synthesis of intermediate 295-1

[0050]

[0051] In a 500mL reaction flask, add benzaldehyde (2.12g, 20mmol), 6-bromo-N1-phenylbenzene-1,2-diamine (5.27g, 20mmol), tetrakis(triphenylphosphine) palladium (5mol%) , sodium metabisulfite (5.70 g, 30 mmol), dichloroethane (200 mL). Reflux for 4 hours. After the reaction was completed, the reaction solution was cooled to room temperature and extracted with dichloromethane 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 intermediate 295-1 (5.94 g, yield 85%). LC-MS: M / Z 348.03 (M+).

[0052] (2) Synthesis of intermediate 295-3

[0053]

[0054] In a 500mL reaction flask, add intermediate 295-1 (21.44g, 61.4mmol), 295-2 (12.36g, 61.4mmol), tetrakis(triphenylphosphine) palladium (5mol%), K2CO3 (17.0g, 122.8mmol ), 1,4-dioxane (200 mL) and ...

Embodiment 2

[0064] Embodiment 2: the synthesis of compound 297

[0065] Compound 297 was synthesized with reference to the method of Example 1 to obtain compound 297 (8.85 g, yield 55%). LC-MS: M / Z 804.28 (M+).

Embodiment 3

[0066] Embodiment 3: the synthesis of compound 313

[0067] Compound 313 was synthesized with reference to the method of Example 1 to obtain compound 313 (8.69 g, yield 54%). LC-MS: M / Z 804.30 (M+).
