[0063] Synthesis of Compound 1
[0064]
[0065] a) Material A-1 (50 mmol) and material B (50 mmol) were dissolved in 300 mL of dry toluene in a 500 mL round bottom flask under nitrogen atmosphere. Sodium tert-butoxide (100 mmol) and 2-dicyclohexylphosphine-2,4,6-triisopropylbiphenyl (10 mmol) were then added to the flask, followed by palladium acetate (2.5 mmol). The reaction was heated to 100°C and stirred for 10 hours. After the reaction, the temperature was lowered to room temperature, the salt and catalyst were removed, the toluene was concentrated, and 200 mL of ethanol was used for recrystallization to obtain intermediate C-1 (16.56 g, 41 mmol yield: 82%).
[0066] b) After intermediate C-1 (40mmol) and intermediate D-1 (40mmol) were completely dissolved in a mixed solution of 150mL toluene and 50mL tetrahydrofuran in a 500mL round bottom flask, p-toluenesulfonic acid (80mmol) was added thereto, The resultant was heated to 50°C and stirred for 2 hours. After the ...

[0068] Synthesis of Compound 7
[0069]
[0070] Compound 7 was prepared according to the synthesis method of Compound 1 in Preparation 1, except that Intermediate F-7 was used instead of Intermediate F-1. Compound 7 was obtained (yield: 82%). ESI-MS (m / z) (M+): theoretical value 577.24, found value 577.54.
