at 20 - 100℃; for 36h; | To a 50 mL round bottom flask was added 1,2,4,5-tetraaminobenzene hydrochloride 1 (284 mg), formic acid (10 mL) at room temperature. The reaction was heated to 100 C for 36 hours. Cooled to room temperature, neutralized to neutral with NaOH solution, filtered and dried. The precipitate was transferred to 50 mL standard Schlenk vials, NaH (80 mg, 60%), 5 mL of toluene, followed by heating to 110 C under nitrogen. After cooling to room temperature, 1-bromobutane (1 mL) and DMF (5 mL) were added, and the mixture was heated to 110C for 4 hours to disappear the starting material. After cooling to room temperature, the inorganic salt was removed by filtration and recrystallized from methylene chloride-methanol to give tetrabutylbenzobisimidazole bromide salt 3a.
