Embodiment
[0040] Add 2.84g of dihydroartemisinin, 4.18g of liquiritin, and 30g of THF solvent into a 100ml three-necked flask, cool down to 0°C with a low-temperature cooling circulation pump, then add 5.2g of PPH3 reagent and 4.0g of DIAD reagent, and the reaction is completed after 24 hours For reaction, the target substance in the solution is refined, the reaction solution is desolvated to remove THF, and 50 g of chloroform is added to wash with water three times, and the obtained organic phase is desolventized. Add 20 g of ethyl acetate and cool down to -10°C for recrystallization to finally obtain 4.2 g of a white solid with a purity of 97% and a yield of 65%.
