Participants

Reaction Steps

In an embodiment, the starting material 10,11-diphenyl-11H-indeno[1,2-b]quinolin-11-ol (385 mg, 1.00 mmol) and 4-methyl-N-phenyl-N-(p-tolyl)aniline (328 mg, 1.20 mmol) are placed in a round bottom flask and then dissolved in 10 ml of dichloromethane. Subsequently, trifluoromethanesulfonic acid (0.13 ml, 1.50 mmol) is slowly dripped into the flask to promote reaction. After 12 hours of reaction at 140° C., the crude product is extracted with 50 ml of Ethyl acetate and sodium bicarbonate for three times. Finally, an organic layer of the crude product is dehydrated with magnesium sulfate and concentrated to be sublimated and purified to obtain 575 mg of 4-(10,11-diphenyl-11H-indeno[1,2-b]quinolin-11-yl)-N,N-di-p-tolylaniline. The percentage yield is 89.7%.
