11 g (50 mmol) of 4-bromobenzoyl chloride was placed in a 300 mL three-necked flask, the inside of the flask was purged with nitrogen, then 50 mL of dichloromethane and 11 g (1.0 × 102 mmol) of benzonitrile were added and the mixture was stirred at 0 ° C. under a nitrogen stream did.After stirring, 5.8 mL (50 mmol) of antimony chloride was added, gradually returned to room temperature from 0 ° C. and stirred at 60 ° C. for 1 hour. After stirring, the mixture was cooled and 80 mL of dichloromethane was added.The mixture was suction filtered to obtain a solid. The obtained solid was washed with dichloromethane to obtain 15 g of a yellow solid. A 1 L four-necked flask was charged with 600 mL of ammonia water and stirred at 0 ° C.A yellow solid was added little by little to this solution and stirred, and the color of the solid changed from yellow to white.The mixture was suction filtered to obtain a solid. The obtained solid was washed successively with water and methanol. After washing, this solid was transferred to a recovery flask, 200 mL of N, N-dimethylformamide was added, and the mixture was stirred at 153 ° C. After stirring, the mixture was suction filtered. The filtrate was transferred again to a recovery flask, and 100 mL of N, N-dimethylformamide was added and stirred at 153 ° C.After stirring, this mixture was suction filtered again. The precipitated solid from the obtained filtrate and filtrate was placed in a recovery flask and distilled under reduced pressure to reduce N, N-dimethylformamide to about 100 mL. To this mixture was added 500 mL of water, and the mixture was stirred and filtered.The resulting solid was washed with water. This solid was added to 500 mL of methanol, irradiated with ultrasonic waves, and suction filtered to obtain 16 g of a white powdery solid (intermediate A-1; 2-bromophenyl-4,6-diphenyltriazine) , Yield 81percent.
