[0260] Synthesis Example 1

[0261] Synthesis of Intermediate 2: Compound 1 (15g, 61mmol), o-nitrophenylboronic acid 1 (10.7g, 64mmol), potassium carbonate 1 (25g, 180mmol), tetrakis (triphenylphosphine) palladium (2.1g, 1.8 mmol) was dissolved in a mixed solution of about 200 mL of toluene and 90 mL of water, replaced with nitrogen, and refluxed for 24 h. After the reaction solution was cooled to room temperature, the organic layer was separated and extracted with ethyl acetate. The organic layer was mixed and dried over anhydrous sodium sulfate. After concentration, it was separated by a chromatography column to obtain a yellow solid with a yield of 70%.

[0262] Synthesis of Intermediate 3: Compound 2 (10 g, 7.8 mmol) was placed in 70 mL of triethyl phosphite and stirred at 170°C. After the reaction is complete, the solvent is removed under reduced pressure, and a light yellow solid is obta...
