Embodiment 1
[0046] Embodiment 1: the synthesis of compound III-7
[0047] 1. Synthesis of intermediate Sub-1
[0048]
[0049]In a 500mL reaction flask, add intermediate Sub-0 (20.45g, 61.4mmol), 1-iodo-2-nitrobenzene (15.29g, 61.4mmol), tetrakis (triphenylphosphine) palladium (5mol%), K2CO3 (17.0 g, 122.8 mmol), 1,4-dioxane (200 mL) and water (50 mL). The temperature of the reaction system was raised to 80° C., and reacted for 12 hours under the protection of nitrogen. After the reaction was completed, 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 recrystallized, and the obtained crude product was passed through a silica gel column to obtain an 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] In a 250ml reaction flask, add Sub-1 (0.33g, 0.98mmol), triethyl phosph...
Embodiment 2
[0067] Embodiment 2: the synthesis of compound III-61
[0068]
[0069] Compound III-61 was synthesized with reference to the method of Example 1, and other steps were referred to the synthesis of compound III-7 to obtain compound III-61 (8.71 g, yield 75%). LC-MS: M / Z 869.35(M+H) + .
Embodiment 3
[0070] Embodiment 3: the synthesis of compound III-102
[0071]
[0072] Compound III-102 was synthesized with reference to the method of Example 1, and the synthesis of compound III-7 was referred to for other steps to obtain compound III-102 (7.76 g, yield 72%). LC-MS: M / Z870.31(M+H) + .
