Embodiment 1
[0051] Embodiment 1: 1 synthesis of compound
[0052]
[0053] Step1. Dissolve 100mmol 1-0 and 200mmol o-nitrophenol in toluene, add 3N potassium hydroxide, 0.1N CuI, 0.1N linphenanthroline, replace with argon three times, and react at 100°C for 6h. After the reaction was completed, the reaction solution was passed through a silica gel funnel, the filtrate was washed with deionized water, concentrated, and the crude product was passed through a silica gel column to obtain 84 mmol of product 1-1.
[0054] Step2. Add 84 mmol of compound 1-1, solvent o-dichlorobenzene, 5 equivalents of triethyl sulfite, replace argon three times, raise the temperature to 165°C for 12 hours, and the reaction takes about 15 hours. The reaction solution was cooled to room temperature, and dichloromethane was added under stirring to dissolve all the product. The organic phase was washed with deionized water, distilled under pressure at 150 degrees Celsius, and concentrated to dryness to obtain a yel...
Embodiment 2
[0056] Embodiment 2: 2 synthesis of compound
[0057]
[0058] Step1. Dissolve 100mmol 1-0 and 200mmol o-nitrothiophenol in toluene, add 3 equivalents of potassium hydroxide, 0.1 equivalent of CuI, 0.1 equivalent of linphenanthroline, replace with argon three times, and react at 100°C 6h. After the reaction was completed, the reaction solution was passed through a silica gel funnel, the filtrate was washed with deionized water, concentrated, and the crude product was passed through a silica gel column to obtain 84 mmol of product 2-1.
[0059] Step2. Add 84 mmol of compound 2-1, solvent o-dichlorobenzene, 5 equivalents of triethyl sulfite, replace argon three times, raise the temperature to 165°C for 12 hours, and the reaction takes about 15 hours. The reaction solution was cooled to room temperature, and dichloromethane was added under stirring to dissolve all the product. The organic phase was washed with deionized water, distilled under pressure at 150 degrees Celsius, ...
