[0126] 1. Preparation of Intermediate 1

[0127] Dissolve starting material 1 (self-made or purchased), alkaline solution and phase transfer catalyst in an organic solvent, add starting material 2 (self-made or purchased), and react at 25°C-50°C. After the reaction was completed, cooled, the solvent was removed from the reaction liquid under reduced pressure, and purified by silica gel column chromatography to obtain intermediate 1. The alkaline solution is selected from sodium hydrogen, potassium tert-butoxide, sodium tert-butoxide, sodium hydroxide, potassium hydroxide, sodium methylate, sodium ethylate, potassium iodide, sodium iodide, etc., preferably potassium tert-butoxide, potassium iodide, iodine Sodium chloride; the organic solvent is selected from tetrahydrofuran, DMF, toluene, acetonitrile, etc., preferably tetrahydrofuran; the phase transfer catalyst is selected from 18-crown-6, tetrabutylammonium iodide, etc., preferably 18-crown-6.
