2-Chloro-1,3-benzenedicarbonitrile

3-Amino-2-carbomethoxy-7-cyano-benzthiophene 1.00 g (3.01 mmol) of 3, 3'-non-9H-carbazole and 1.66 g (12.0 mmol) of potassium carbonate were placed in a 100 ml three-necked flask, and the flask was purged with nitrogen. N, N-dimethylformamide (24.0 ml) was added to the mixture, and the mixture was stirred at room temperatureAnd stirred for 2 hours. After 1.80 g (11.1 mmol) of In a 500-mL round-bottom flask, is added p-CP-2Br (1.2 equiv.) and 250 mL of anhydrous THF. The solution is placed in dry ice / acetone bath for 15 mm before dropwisely adding nBuLi (2.5 M in n-hexane, 1.3 equiv.) to result in a yellow slurry. The reaction mixture is allowed to stir at -78 C for 0.5 h. Then THF solution (30 mL) of 1.63 g (10.0 mmol) of 2-chloro-1 , 3-dicyano-benzene, 2.07 g (10.0 mmol) of 6H- benzimidazolo[1 , 2-a]benzimidazole and 2.12 g (10.0 mmol) of tripotassium phosphate in 50 ml of DMF are stirred for 24 h at 150 C. The reaction mixture is cooled at room temperature and added water, then the precipitate is filterted off. Gradient column chromatography on silica gel with dichloromethane/ethyl acetate (dichloromethane100%, 9/1 , 4/1 ) gives the product. Yield 2.80 g (84 %). 1H NMR (400 MHz, CDCI3): delta 8.19 (d, 2H); 7.95 - 7.87 (m, 2H); 7.86 (t, 1 H); 7.79 (dd, 1 H); 7.49 (td, 1 H); 7.46 - 7.35 (m, 3H); 7.15 (dt, 1 H).A mixture of 3, 3?-dicarbazyl (3 mmol, 1 g),
