Embodiment 1

[0139] Example 1: Synthesis of compound 3

[0140]

[0141] Weigh compound 1 (1.0g, 984μmol), compound 2 (1.25g, 2.4mmol), Pd 2 (dba) 3 .CHCl 3 (120mg, 116μmol), HP(tBu) 3 BF 4 (70mg, 241μmol) was added to a 500mL two-necked round bottom flask under a nitrogen atmosphere, degassed THF (300mL) was added to the above two-necked flask, and then K was added dropwise to the reaction system 2 CO 3 Aqueous solution (1M, 15.0 mL, 15.0 mmol), stirring at room temperature overnight. The reaction system gradually turned blue. After 24 hours, first evaporate and concentrate most of the solvent in the solution, then extract the solution with dichloromethane / water, collect the organic phase, dry the organic phase with anhydrous sodium sulfate, filter, remove the solvent by rotary evaporation, and separate with a silica gel column The product, the eluent was dichloromethane: n-hexane (1:4), 1.4 g of blue solid compound 3 was obtained, and the yield was 88%. The characterization data are as fol...

Embodiment 2

[0143] Example 2: Synthesis of Compound 4

[0144]

[0145] The compound TBAF (270 mg, 855 μmol) was weighed and dissolved in 2 mL of THF to form a homogeneous solution. Take another 50mL reaction flask, weigh compound 3 (120mg, 73.2μmol) and dissolve it in 5mL THF, and dissolve it fully. 2ml of TBAF in THF was added dropwise to the compound 3 solution, and stirred at room temperature for 15 minutes. The reaction mixture was dropped into 30 ml of methanol, and the resulting precipitate was collected. The crude product obtained by precipitation was purified and separated by a silica gel chromatography column, and the eluent was dichloromethane: n-hexane (1: 3) to obtain 90 mg of compound 4 with a yield of 90%. The characterization data are as follows:
