Embodiment 1

[0164] Embodiment 1: the synthesis of compound 39

[0165] Dissolve 1.3g (0.005mol) of 1a in 10ml of N,N-dimethylformamide, add 0.83g of potassium carbonate, stir for 0.5h, add 1.26g of 2a in batches, heat up to 80°C after addition, and stir for 8h . After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated saline, extracted three times with 100 ml of ethyl acetate, and dried. After precipitation, it was purified by column chromatography to obtain 2.1 g of an oily product.

[0166]

Embodiment 2

[0167] Embodiment 2: the synthesis of compound 15

[0168] Dissolve 1.15g (0.005mol) of 1b in 10ml of N,N-dimethylformamide, add 0.83g of potassium carbonate, stir for 0.5h, add dropwise the DMF solution of 2b (1.4g), and heat up to 80°C after adding , Stir the reaction for 8h. After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated saline, extracted three times with 100 ml of ethyl acetate, and dried. After precipitation, it was purified by column chromatography with petroleum ether: ethyl acetate 1000:1-300 eluent to obtain 1.75 g of an oily product.

[0169]

Embodiment 3

[0170] Embodiment 3: the synthesis of compound 207

[0171] Dissolve 2.0g (0.005mol) of 1c in 10ml of N,N-dimethylformamide, add 0.83g of potassium carbonate, stir for 0.5h, add 1.45g of 2c in batches, heat up to 80°C after addition, and stir for 8h . After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated saline, extracted three times with 100 ml of ethyl acetate, and dried. After precipitation, it was purified by column chromatography with petroleum ether: ethyl acetate 1000:1-200 eluent to obtain 2.6 g of an oily product.
