[0084]
[0085] Concrete synthetic steps are as follows:
[0086] (1) Synthesis of compound 3
[0087]
[0088] Weigh 5.0g (0.018mol) of compound 1 and 10g (0.048mol) of compound 2 and dissolve in 100mL of acetone, then add 7.9g (0.057mol) of K 2 CO 3 , to prepare a reaction mixture solution, and then the reaction mixture solution was heated to reflux for 12 hours. The solution after the reaction was completed was filtered, and the residue obtained after removing the solvent was purified through a silica gel purification column to obtain 3.0 g of compound 3 as a white solid.
