specific Embodiment

[0177] The synthesis method of the polycyclic compound according to the present invention is exemplified, but the present invention is not limited to the following examples.

[0178] 1. Synthesis of compound (1)

[0179]

[0180] 1) Synthesis of intermediate 1-3: under nitrogen atmosphere, (18.2g, 100mmol) of compound 1-1, (17.5g, 100mmol) of compound 1-2, (39.1g, 120mmol) of cesium carbonate and 200mL Add N,N-dimethylformamide into a 500mL three-neck flask, heat to 150°C and react for 12 hours. After the reaction is complete, cool the reaction solution to room temperature. In water, the precipitated solid was subjected to suction filtration, and the filter residue was collected for recrystallization and purification to obtain intermediate 1-3 with a yield of 85%.

[0181] 2) Synthesis of intermediate 1-5: under nitrogen atmosphere, (23.5g, 70mmol) of compound 1-3, (17.6g, 70mmol) of compound 1-4, (29.3g, 90mmol) of cesium carbonate and 150mL Add N,N-dimethylformamide into ...
