[0173]
[0174] Synthesis of Compound C-1:
[0175]
[0176] Weigh magnesium (1.49g, 62mmol) and iodine into a 250mL three-necked flask, add 25ml of anhydrous tetrahydrofuran, replace nitrogen and add 4-bromotriphenylamine (10g, 31mmol), heat to initiate the reaction, and place at 65°C for 2h. The Grignard reagent was prepared after the reaction liquid was cooled to room temperature. Weigh cyanuric chloride (5.67g, 31mmol) into a 250mL flask, and add about 80mL of tetrahydrofuran. After replacing the nitrogen, the Grignard reagent was added slowly, and stirred overnight at room temperature. After the reaction was complete, it was quenched with water, extracted with ethyl acetate, dried over anhydrous sodium sulfate, mixed with silica gel and purified by column chromatography to obtain 4.85 g of an interme...
