Participants

Reaction Steps

To a solution of 400 mg of 4,4'-bis(3-diethylaminopropyl)biphenyl in 4 ml of ethanol was added 0.84 ml of ethyl iodide, and the mixture was refluxed for 3 hours. After adding further 0.42 ml of methyl iodide, the mixture was refluxed for 2 hours and concentrated under a reduced pressure. To the concentrate were added 5 ml of acetone and 50 ml of ethyl acetate. The resulting crystal was collected by filtration, washed with ethanol, acetone and n-hexane, and dried under a reduced pressure. The obtained pale yellow powder was recrystallized from 10 ml of ethanol to obtain 475 mg of the title compound as a pale yellow crystal.
