YieldReaction ConditionsOperation in experiment
46% In an argon atmosphere, 10 g (29 mmol) of 1-(4-bromophenyl)-phenyl-1H-benzimidazole were dissolved into 100 mL of dehydrated THF, and the temperature of the solution was cooled to -78 C. Then, 20 mL of n-butyllithium (in hexane, 1.6 mol/L) were dropped. After the mixture had been stirred at -78 C for 1 hour, the temperature of the mixture was increased to 0C. The temperature of the mixture was cooled to -78 C again, and 9.7 mL (87 mmol) of trimethoxyborane were dropped. The mixture was stirred at -78 C for 1 hour, and was then stirred at room temperature for 2 hours. 100 mL of 10-mass% hydrochloric acid were added, and the whole was stirred for 1 hour, followed by filtration. The organic layer of the filtrate was washed with a saturated sodium chloride solution and dried with magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by means of silica gel column chromatography to obtain 4.2 g of 4-(2-phenyl-1H-benzimidazol-1-yl)phenylboronic acid (46% yield).

Then, 10 mL of a 2 M aqueous solution of sodium carbonate were added, and the whole was refluxed under heating for 8 hours in an argon atmosphere. After the completion of the reaction, the resultant was filtered, and the resultant solid was washed with water, methanol, and toluene to obtain 1.7g of a greenish white solid (84% yield) . Mass spectral analysis confirmed that the solid was a target product. The solid had an m/e of 698 with respect to a molecular weight of 698.27.

93.41% In a 1000 ml three-necked flask, equipped with mechanical stirring, Ar gas protection, add 25. lg of the bromine synthesized in the third step (molecular weight 348, 0.072 mol 1), 300 ml of anhydrous THF, cooled to -78 C, stirred 35ml of BuLi (2 · 4M, 0.084mol) was added dropwise, the temperature was maintained at _78 C, and after stirring for 10 min, 40 ml of B(0iPr) 3 (molecular weight 188.07, specific gravity 0.9574, 0.204 mol) was added dropwise at -78 C. After stirring to room temperature (with 3 hrs), dilute acid is added to hydrolyze, the aqueous layer is separated, neutralized to neutrality, sodium chloride is added, hydrazine HF dissolved in water is distilled off under reduced pressure, and a white solid is precipitated and filtered to obtain a product. 21 g of solid product, yield 93.41%.
80% Under nitrogen protection,In a 1000ml three-neck bottle,30 g (85.96 mmol, 1 eq) of the compound 1- (4-bromophenyl) -2-phenyl-1H-benzo [d] imidazole was added to 300 mL of tetrahydrofuran,Cooling down to minus 78 degrees,39.4 mL (94.56 mmol, 1.1 eq) of n-BuLi was slowly added dropwise to the above reaction solution,Incubation reaction for 1.5h,Subsequently, 32.3 g (171.92 mmol, 2 eq) of triisopropyl borate was slowly added dropwise to the above reaction solution,Naturally warmed to room temperature and stirred overnight to stop the reaction,Add 100 mL of a 1 mol / L dilute hydrochloric acid solution and stir at room temperature for 1 h.The layers were separated, and the aqueous phase was extracted with 200 mL of dichloromethane * 1. The organic phases were combined.Spin-drying gave 21.67 g of a white solid with a yield of 80%.
76.8% With n-butyllithium; In tetrahydrofuran; at -78℃; Synthesis of Intermediate 5-D: In a 250ml three-necked round flask, added was Intermediate 5-C(11.5g, 0.03mol), and 120ml dried THF that underwent treatment with Na /Benzophenone. Liquid nitrogen was used to cool reaction to -78C. While stirring, slowly added dropwise 14.5ml of n-butyllithium (0.036mol, 2.5mol·L-1), and Triisopropyl borate 9.96ml (8.12g, 0.043mol). After the addition was completed, stirred to room temperature. Adding an appropriate amount of dilute hydrochloric acid, hydrolysis, extraction with ethyl acetate, the combined organic phases. The organic solvent was removed by rotary evaporation to give the crude product. After recrystallization from ethanol to give a white solid 7.23g, yield 76.8%.
