실험 절차

A solution of 21.9 g (0.1 mole) of 4-(N-2-hydroxyethyl-N-ethylamino)cinnamaldehyde, 9.3 g (1 mole) of aniline, and 0.19 g (1 mole %) of toluenesulfonic acid in toluene is heated at reflux for 17 hours with azeotropic removal of water. After the mixture is cooled to room temperature, 17.2 g (0.2 mole) of methacrylic acid and 18.1 g (0.1 mole) of 4-nitrophenylacetic acid are added to the solution, and the reaction is stirred at room temperature for 3 hours. The mixture then is heated at reflux for 16 hours. After cooling to room temperature, the solid diphenylbutadiene precipitates from solution and is collected by filtration and purified by recrystallization from ethanol.
