[0235] Example 1: Platinum complex PT3 can be synthesized as follows:

[0236]

[0237]

[0238]

[0239] The synthesis of intermediate 1: 2-bromipateazole (7.38 g, 30 mmol, 1.0 equivalents) were sequentially added to 100 ml dry three flasks with magnetic rotor and condensed tube (113.8 mg, 0.3 mmol, 0.01 equivalents), 1-methylimidazole (49.26 mg, 0.6 mmol, 0.02 equivalents), t-butanol (4.84 g, 60 mmol, 2.0 equivalents). The nitrogen gas was discharged three times, then 2-bromo-4-tert-butylpyridine (7.71 g, 36 mmol, 1.2 equivalents), 1-methylimidazole (49.3 mg, 0.6 mmol, 0.02 equivalents), 50 ml of toluene The oil bath temperature was raised to 130 ° C for 24 hours. Cooling to room temperature, distillation under reduced pressure, removes the solvent, then dry, separately, the silica gel column chromatography column is separated and purified, the eluent is petroleum ether / ethyl acetate = 20: 1, to obtain a white solid 11.31 g, receive 99%. 1 H NMR (500 MHz, DMSO- d 6 : δ 1...

Embodiment 2

[0252] Example 2: Platinum complex PT14 can be synthesized as follows:

[0253]

[0254] Synthesis of intermediate 10: Joint intermediate 4 (6.90 g, 30 mmol, 1.0 equivalents), 2,5-dimethylbenzonic acid (3.84 g, "in a 100 ml dry three flask with magnetic rotor and condenser tube (3.84 g, 31.5 mmol, 1.05 equivalents), PD (PPH 3 ) 4 (1.04 g, 0.9 mmol, 0.03 equivalents), K 2 CO 3 (8.29 g, 60 mmol, 2.0 equivalents), the nitrogen was switched three times, and 1,4-dioxane (30 mL) and H were added under nitrogen protection. 2 O (15 ml). The oil bath temperature was raised to 100 ° C for 6.0 hours, cooled to room temperature, extracted three times with 30 mL of ethyl acetate, with anhydrous NA 2 SO 4 The organic phase was dried, then filtered, distilled under reduced pressure, the solvent was removed, and the dry method was separated and purified, the column chromatography column was separated and purified, the eluent was petroleum ether / ethyl acetate = 20: 1 to give a white solid 5.29...
