[0248] Preparation Example 1 Preparation of Compound (1)
[0249]
[0250] Preparation of compound (A)
[0251] Carbazole (20g, 119.6mmmol), methyl 2-iodobenzoate (26.4mL, 179.4mmol), K 2 CO 3 (21.5g, 155.5mmol), Cu (1.52g, 23.9mmol) and CuI (1.14g, 5.98mmol) were dissolved in dibutyl ether (500mL), and the solution was stirred at reflux for 48 hours under an argon atmosphere. After the reaction was completed, the reaction mixture was cooled to room temperature and extracted with water (800 mL). The organic layer was evaporated under reduced pressure. The residue was purified by column chromatography with hexane and ethyl acetate (4:1), and recrystallized from ethanol (300 mL) to obtain compound (A) (24.5 g, 68%).
[0252] Preparation of compound (B)
[0253] Compound (A) (15.0 g, 49.8 mmol) was dissolved in diethyl ether (100 mL), and the solution was frozen to -78°C. Methyl lithium (1.6M in diethyl ether, 78 mL, 124.4 mmol) was added thereto, and the mixture was sti...

[0260] Preparation Example 2 Preparation of Compound (320)
[0261]
[0262] Preparation of compound (E)
[0263] Compound (C) (7 g, 24.7 mmol) was dissolved in dichloromethane (100 mL), and N-bromosuccinimide (10.5 g, 59.2 mmol) was added thereto at 0°C. Maintaining this temperature, the solution was stirred for 5 hours. Distilled water (150 mL) was added to terminate the reaction, the mixture was extracted with dichloromethane (100 mL), and the extract was evaporated under reduced pressure. Compound (E) (7.4 g, 68%) was obtained by recrystallization from ethanol / acetone (1:2 v / v).
[0264] Preparation of compound (320)
[0265] Compound (E) (5g, 13.8mmol), phenylboronic acid (3.8g, 30.36mmol) and Pd(PPh 3 ) 4 (1.6 g, 1.04 mmol) was dissolved in toluene (100 mL) and ethanol (50 mL), and 2M aqueous sodium carbonate solution (50 mL) was added thereto. After stirring under reflux at 120°C for 4 hours, the reaction mixture was cooled to 25°C, and distilled water (200 mL)...

[0268] Preparation of compound (F)
[0269] Carbazole (20g, 119.6mmmol), methyl 5-bromo-2-iodobenzoate (26.4mL, 179.4mmol), K 2 CO 3 (21.5g, 155.5mmol), Cu (1.52g, 23.9mmol) and CuI (1.14g, 5.98mmol) were dissolved in dibutyl ether (500mL), and the solution was stirred at reflux for 48 hours under an argon atmosphere. After the reaction was completed, the reaction mixture was cooled to room temperature and extracted with water (800 mL). The organic layer was evaporated under reduced pressure. The residue was purified by column chromatography with hexane and ethyl acetate (4:1), and recrystallized from ethanol (300 mL) to obtain compound (F) (24.5 g, 58%).
[0270] Preparation of compound (G)
[0271] Compound (F) (15.0 g, 49.8 mmol) was dissolved in diethyl ether (100 mL), and the solution was frozen to -78°C. To this was added methyllithium (1.6M in diethyl ether, 78 mL, 124.4 mmol), and the compou...
