2-Chloro-4,6-diphenyl-1,3,5-triazine → HCID 66797655, compound

Participants

Reaction Steps

10 g (35.17 mmol) of 10,10-dimethyl-10,12-dihydro-3,12-diazaindeno-[2,1-b]fluorene are dissolved in 150 ml of dimethylformamide under a protective-gas atmosphere, and 1.7 g of 60% NaH in mineral oil (42.2 mmol) are added. After 1 h at room temperature, a solution of 2-chloro-4,6-diphenyl-1,3,5-triazine (10.7 g, 38.68 mmol) in 100 ml of THF is added dropwise. The reaction mixture is stirred at room temperature for 12 h. After this time, the reaction mixture is poured onto ice and extracted three times with dichloromethane. The combined organic phases are dried over Na2SO4 and evaporated. The residue is extracted with hot toluene, recrystallised from toluene and finally sublimed in a high vacuum, the purity is 99.9%. The yield is 14.4 g (80%).
