[0147]
[0148] Synthesis of compound 1-1
[0149] After pyrrole (10 g), benzaldehyde (0.52 equivalents), trifluoroacetic acid (2 drops) and anhydrous tetrahydrofuran (100 mL) were mixed in a flask, the mixture was stirred at room temperature under nitrogen for 5 hours. After confirming the disappearance of the starting material using TLC, bromine (1.0 eq) was added thereto at -78°C. After the reaction was completed, triethylamine (3 equivalents) and ethanol were introduced thereinto, and the resultant was thoroughly stirred. The solid produced here was filtered to obtain compound 1-1 (14.8 g, yield 52%).
[0150] Synthesis of Compound 1-2
[0151] Compound 1-1 (14.8 g) was dissolved in chloroform, and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) (1.0 equivalent) was added thereto at 0°C. The resultant was stirred at room temperature for 1 hour, and then triethylamine (2.0 equivalents) was slowly added dropwise thereto. After the resultant was stirred at room tempera...

[0155]
[0156] Synthesis of Compound 2-1
[0157] After compound 1 (2.0 g) was dissolved in a dichloromethane solvent, chlorosulfonyl isocyanate (3 equivalents) was introduced thereto. The reaction was allowed to proceed at room temperature and determined after removing a small amount and mixing with dimethylformamide. When the reaction was complete, dimethylformamide (10 equivalents) was introduced thereto, and the resultant was stirred for about 3 hours. The resultant was extracted with water and chloroform, and then the organic layer was dried with sodium sulfate and purified as a solid with methanol to obtain compound 2-1 (1.8 g, yield 87%).
[0158] Synthesis of compound 2
[0159] Compound 2-1 (1.8 g), potassium cyclohexyltrifluoroborate (2.5 equivalents) and manganese acetate hydrate (5 equivalents) were introduced into a dimethylformamide solvent and heated to 80° C. or lower. When the reaction was completed, the resultant was cooled to room temperature, and aft...

[0162] Synthesis of compound 3-1
[0163] After pyrrole (10 g), benzaldehyde (0.52 equiv), trifluoroacetic acid (2 drops) and anhydrous dichloromethane (500 mL) were mixed in a flask, the mixture was stirred at room temperature under nitrogen for 5 hours. After confirming the disappearance of the starting material using TLC, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) (0.52 equivalent) was added thereto at 0°C. After the resultant was stirred at room temperature for 1 hour, triethylamine (2.5 equivalents) was slowly added dropwise thereto. The resultant was stirred at room temperature for 30 minutes, and then 5-bromo-5H-dibenzoborole (4.6 equivalents) was slowly added dropwise thereto. The reaction mass was stirred at room temperature for 5 hours, and after water was introduced thereinto, extracted with dichloromethane. The resultant was dried over anhydrous magnesium sulfate, filtered, and vacuum distilled to remove the solvent. The resultant was passed thr...
