example 1
[0074] Example 1: Preparation of Compound D-2
[0075]
[0076] Preparation of compound 1-1
[0077] 2-Phenylpyridine (10.0g, 32.0mmol), iridium(III) chloride hydrate (IrCl 3 ·xH 2 O) (8.1 g, 29.0 mmol), 2-ethoxyethanol (220.0 mL) and H 2 O (74.0 mL) was stirred in the flask at 140 °C for 24 hours. After the reaction was complete, the mixture was cooled to room temperature and washed with H 2 Washed with O and methanol (MeOH), and then dried to obtain compound 1-1 (11.0 g, 71%).
[0078] Preparation of compound 1-2
[0079] Compound 1-1 (10.0 g, 9.0 mmol) was dissolved in dichloromethane (MC) (4.0 L) in a flask. Silver triflate (AgOTf) (5.0 g, 19.0 mmol) dissolved in MeOH (400.0 mL) was slowly added thereto and the mixture was stirred at room temperature for 12 hours. After the reaction was completed, the reaction mixture was filtered and the filtrate was dried to obtain compound 1-2 (12.0 g, 94%).

[0085] Example 2: Preparation of Compound D-3
[0086]
[0087] Preparation of compound 2-1
[0088] 2-Bromo-5-methylpyridine (15.0g, 87.0mmol), phenylboronic acid (14.0g, 114.0mmol), Pd(PPh 3 ) 4 (3.0g, 2.6mmol), K 2 CO 3 (36.0g, 260.0mmol), toluene (300.0mL), EtOH (150.0mL) and H 2 O (130.0 mL) was stirred in the flask at 100 °C for 3 hours. After the reaction was complete, the mixture was extracted with EA, by using MgSO 4 The remaining water was removed and the mixture was distilled under reduced pressure. By column chromatography with MC / Hx=1 / 2, compound 2-1 (10.0 g, 68%) was obtained as a white solid.
[0089] Preparation of Compound 2-2
[0090] Compound 2-1 (10.0g, 30.0mmol), IrCl 3 ·xH 2 O (8.0 g, 27.0 mmol), 2-ethoxyethanol (200.0 mL) and H 2 O (70.0 mL) was stirred in the flask at 140 °C for 24 hours. After the reaction was complete, the mixture was cooled to room temperature and washed with H 2 Washed with O and MeOH, and then dried to obtain ...

[0096] Example 3: Preparation of Compound D-95
[0097]
[0098] Preparation of compound 3-1
[0099] 2-Bromo-4-methylpyridine (10.0g, 63.0mmol), dibenzo[b,d]furan-4-ylboronic acid (15.0g, 76.0mmol), Pd(PPh 3 ) 4 (2.2g, 2.0mmol), Na 2 CO 3 (20.0g, 19.0mmol), toluene (300.0mL), EtOH (150.0mL) and H 2 O (10.0 mL) was stirred in the flask at 100 °C for 2 hours. After the reaction was complete, the mixture was cooled to room temperature and extracted with EA. By using MgSO 4 The remaining water was removed and the mixture was distilled under reduced pressure. By column chromatography with MC / Hx=1 / 3, Compound 3-1 (11.0 g, 67%) was obtained as a white solid.
[0100] Preparation of Compound D-95
[0101] MeOH (200.0 mL) and EtOH (100.0 mL) were added to compound 3-1 (7.0 g, 28.0 mmol) and compound 2-3 (10.0 g, 14.0 mmol) in a flask and the mixture was stirred at reflux for 12 hours. After the reaction was complete, the mixture was cooled to room temperature and fi...
