실험 절차
101.4 g of triphenylamine and 35.5 mL of DMF were placed in a three-neck flask, and while stirring with cooling in ice water, 84.4 mL of phosphorus oxychloride was dripped into the flask; the reaction mixture was hold at 95° C. for 5 hours. It was poured into 4 L of hot water and stirred for 1 hour. The precipitate was then collected and washed with a 1:1 mixture of ethanol/water, and 4-(N, N-diphenylamino) benzaldehyde was obtained. The yield was 91.5 g (81.0%).
