Example Embodiment
[0046]Example 1: Synthesis of compound III-7
[0047]1. Synthesis of Intermediate Sub-1
[0048]
[0049]Add intermediate Sub-0 (20.45g, 61.4mmol), 1-iodo-2-nitrobenzene (15.29g, 61.4mmol), tetrakis (triphenylphosphine) palladium (5mol%), K2CO3 into a 500mL reaction flask (17.0 g, 122.8 mmol), 1,4-dioxane (200 mL) and water (50 mL). The reaction system was heated to 80°C and reacted for 12 hours under nitrogen protection. After the completion of the reaction, the reaction solution was cooled to room temperature and extracted with o-dichlorobenzene and water. The organic layer was dried with anhydrous magnesium sulfate, concentrated, and the crude product obtained by recrystallization was passed through a silica gel column to obtain Intermediate Sub-1 (15.11 g, yield 75%). LC-MS: M / Z 326.99(M+H)+.
[0050]2. Synthesis of Intermediate Sub-2
[0051]
[0052]Add Sub-1 (0.33g, 0.98mmol), triethyl phosphite (0.25g, 1.47mmol), nitrogen to a 250ml reaction flask
[0053]React overnight at 145°C under protectio...
