[0078] [Preparation Example 1] Preparation of Compound 1
[0079]
[0080] Preparation of Compound 1-1
[0081] At 100°C, p-2-iodobenzene (30 g, 120.4 mmol), 4-bromophenylboronic acid (26 g, 132.5 mmol), Pd (PPh 3 ) 4 (6.9 g, 6.02 mmol), 150 ml 2M Na 2 CO 3 and 500 ml of toluene for heating. After 4 hours, the mixture was cooled to room temperature, extracted with ethyl acetate (EA), washed with distilled water, washed with anhydrous MgSO 4 Drying, distillation under reduced pressure, and column separation gave compound 1-1 (28 g, 100.68 mmol, 83, 33%).
[0082] Preparation of compound 1-2
[0083] Compound 1-1 (28 g, 100.68 mmol) was mixed with 300 mL of triethyl phosphite, and stirred at 150° C. for 6 hours. The mixture was cooled to room temperature, distilled under reduced pressure, extracted with EA, and washed with distilled water. Subsequently, with anhydrous MgSO 4 Drying, distillation under reduced pressure, and column separation gave compound 1-2 (11 g, 4...

[0100]
[0101] Preparation of compound 2-1
[0102] Dibenzo[b,d]thiophen-4-ylboronic acid (10 g, 43.84 mmol), bromonitrobenzene (8.85 g, 43.84 mmol), 70 mL of 2M Na 2 CO 3 The aqueous solution, 200 ml of toluene and 70 ml of ethanol were mixed and stirred under reflux. After 5 hours, the mixture was cooled to room temperature, extracted with EA, washed with distilled water, washed with anhydrous MgSO 4 Dry and distill under reduced pressure. Subsequently, column separation was performed to obtain compound 2-1 (10 g, 32.74 mmol, 74.68%).
[0103] Preparation of Compound 2-2
[0104] Compound 2-1 (10 g, 32.74 mmol) was mixed with 100 mL of triethyl phosphite, and stirred at 150° C. for 7 hours. The mixture was cooled to room temperature, and distilled under reduced pressure. Subsequently, recrystallization was performed using EA to obtain compound 2-2 (7 g, 25.60 mmol, 78.19%).

[0112] [Preparation Example 3] Preparation of Compound 19
[0113]
[0114] Preparation of compound 3-1
[0115] 2-(Phenylamino)benzoic acid (50 g, 0.23 mol) was dissolved in 1 L of MeOH, placed in an ice bath, and stirred at 0° C. for 10 minutes. Slowly add SOCl at 0 °C 2 (60 mL, 0.58 mol), and the mixture was stirred at 90° C. under reflux for 12 hours. After the reaction was terminated, the mixture was washed with distilled water and extracted with EA. with anhydrous MgSO 4 The organic layer was dried and the solvent was removed using a rotary evaporator. Subsequently, column chromatography purification was performed using EA as a developer to obtain compound 3-1 (47 g, 92%).
[0116] Preparation of compound 3-2
[0117] Compound 3-1 (90 g, 0.3 mol) was added to 1.5 L of THF, MeMgBr (3.0 M) (462 mL, 1.38 mol) was added slowly, and the mixture was stirred at room temperature for 12 hours. After the reaction was terminated, the mixture was neutralized with distilled...
