Embodiment 1
[0071] Embodiment 1: the preparation of compound 1
[0072]
[0073] Compounds 1-1 (5.16 g, 20 mmol), 1-2 (4.14 g, 20 mmol) and sodium ethoxide were completely dissolved in 100 ml of ethanol in a round bottom flask, and the resulting solution was heated and stirred. After the reaction was completed, the residue obtained by concentrating the obtained product under reduced pressure was diluted with tetrahydrofuran, and washed with water and brine. The organic solvent layer was collected, water was removed over anhydrous magnesium sulfate, and the residue was filtered, then concentrated under reduced pressure. The concentrated solution was purified by silica gel column chromatography to prepare compound 6.70 g of compound 1-3, yield 75%.
[0074] Under the protection of nitrogen, 1-3 (44.70g, 100mmol), 1-4 (38.62g, 100mmol), potassium carbonate (1.24g, 9.00mmol), and toluene 200mL were added into a 2L reactor and stirred. The temperature in the reactor was raised to 70°C, an...
Embodiment 2
[0075] Embodiment 2: the preparation of compound 2
[0076]
[0077] Compound 2 was obtained by replacing 1-4 in Example 1 with 2-4 as shown above. Mass Spectrum m / z: 627.19 (calculated: 627.11).
