실험 절차

Into a three-necked flask, 101.4 g of triphenylamine and 35.5 ml of DMF (dimethylformamide) were placed, and 84.4 ml of phosphorus oxychloride was added dropwise thereto with stirring while cooling with ice water, and then the temperature was raised to 95° C. to carry out reaction for 5 hours. The reaction solution obtained was poured into 4 liters of warm water, followed by stirring for 1 hour. Thereafter, the precipitate formed was collected by filtration, and washed with a mixture of ethanol/water (1:1) to obtain 4-(N,N-diphenylamino)benzaldehyde in an amount of 91.5 g (yield: 81.0%).
