YieldReaction ConditionsOperation in experiment
30%; 60% With water; potassium iodide; In N,N-dimethyl-formamide; at 80℃; for 24h;Molecular sieve; In the case where water is contained in the reaction, as shown in the following reaction formula, it is confirmed that benzimidazole having a functional group of boronic acid protected by a protecting group is produced in less than 70% and side reaction is proceeded by 30% or more, This is because in the presence of water, the protective group-protected moiety is hydrolyzed to boronic acid, so that the boronic acid reacts directly with the amine.

61% General procedure: To a stirred solution of 2,3,6,7-tetrakis(4-bromophenyl)-4,8-didecylbenzo[1,2-b:4,5-b′]difuran (7) (0.318g, 0.3mmol), an appropriate boronic acid MIDA ester (1.8mmol), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (0.066g, 0.09mmol), an argon degassed 1,4-dioxane (6mL) was added. The resulting mixture was stirred at room temperature for 5min under argon atmosphere. Tripotassium phosphate (3M aqueous solution, 1.2mL) was added and the mixture was stirred at 80C for 22h. Reaction mixture was cooled to rt and transferred into a separatory funnel. Chloroform (50mL) and 10% sodium hydroxide (10mL) were added and the layers were separated. Aqueous layer was extracted with chloroform (3×50mL). Combined organic layers were dried over anhydrous magnesium sulfate and concentrated. The crude product was crystallized from chloroform/methanol or p-xylene.
