Embodiment 1
[0041] Embodiment 1: 1 synthesis of compound
[0042]
[0043] Step1. Dissolve 100 mmol of phloroglucinol and 100 mmol of o-fluoronitrobenzene in DMF, add 3 equivalents of potassium tert-butoxide, and 0.05 equivalents of phase transfer catalyst at 100°C for 6 hours. After the reaction was completed, the reaction solution was poured into water, filtered to obtain a filter cake, and the crude product was passed through a silica gel column to obtain 84 mmol of product 1-1.
[0044]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 yellow oily viscous liquid. ...
Embodiment 2
[0046] Embodiment 2: 2 synthesis of compound
[0047] The synthetic method is the same as in Example 1, and the phloroglucinol in Step1. is replaced with phloroglucinol.
Embodiment 3
[0048] Embodiment 3: 3 synthesis of compound
[0049]
[0050] Step1. Dissolve 100 mmol of phloroglucinol and 100 mmol of o-fluoronitrobenzene in DMF, add 3 equivalents of potassium tert-butoxide, and 0.05 equivalents of phase transfer catalyst at 100°C for 6 hours. After the reaction was completed, the reaction solution was poured into water, filtered to obtain a filter cake, and the crude product was passed through a silica gel column to obtain 84 mmol of product 1-1.
[0051] 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.
