2. Adjust PH=1 of the obtained reaction solution with hydrochloric acid aqueous solution, and then extract the water layer of the reaction solution with dichloromethane. After that, adjust PH=10 of the reaction solution with sodium hydroxide aqueous solution, and then extract and stratify with dichloromethane. After the organic phase anhydrous sodium sulfate is dried, the solvent is evaporated to obtain yellow oil;
3. Dissolve the oily substance in 8ml of isopropanol, then add 20ml of 3M hydrochloric acid butanol solution, stir at room temperature for 1h, and obtain white colloidal substance;
4. Add 100ml of ether into the white colloid, stir for 30min to obtain a large amount of white solids, filter and collect solids;
