YieldReaction ConditionsOperation in experiment
24% General procedure: To a well-stirred suspension of 4.0 g (100 mmol) of sodium hydride, 60percent by weight dispersion in mineral oil, in 500 mL of THF are added in portions while cooling with ice, at about +10° C., 16.7 g (100 mmol) of carbazole [51555-21-6]?Caution Evolution of hydrogen Foaming After the addition has ended, the mixture is stirred for a further 30 min and then 20.7 g (100 mmol) of 1,3,5-tricyano-2-fluoro-4,6-dichlorobenzene [25751-93-7] are added in portions while cooling with ice in such a way that the temperature does not exceed +20° C. After the addition has ended, the mixture is stirred at +10° C. for a further 2 h, then the cooling bath is removed, and the mixture is allowed to warm to 20-25° C., stirred for a further 2 h and then heated to 40° C. for another 6 h. After cooling to room temperature, 12.0 g (300 mmol) of sodium hydride, 60percent by weight dispersion in mineral oil, are added, the reaction mixture is cooled to +10° C., and then 95.8 g (300 mmol) of <strong>[56525-79-2]3,6-diphenylcarbazole</strong> [56525-79-2] are added in portions?Caution Evolution of hydrogen Foaming After the addition has ended, the mixture is stirred at +10° C. for a further 2 h, then the cooling bath is removed, and the mixture is allowed to warm to 20-25° C., stirred for a further 2 h and then heated to 60° C. for another 16 h. After cooling to room temperature, the reaction is ended by dropwise addition of 30 mL of MeOH and the reaction mixture is then concentrated almost to dryness under reduced pressure. The residue is subjected to hot extractive stirring twice with 600 mL each time of a mixture of 400 mL of methanol and 200 mL of water and then once with 500 mL of methanol. Purification is effected by recrystallization from dioxane (about 3.5 mL/g) three times, then recrystallization from DMF (about 2 mL/g) five times and fractional sublimation twice (p about 1×10?5mbar, T about 330-340° C.). Yield: 22.9 g (24.0 mmol) 24percent. Purity: 99.9percent by HPLC.
