反応手順

18 g of 50% by weight sodium hydroxide solution were added dropwise to 17.7 g of p-diethylaminobenzaldehyde and 26.4 g of acetophenone in 150 ml of ethanol at 20° C. The mixture was then stirred at 20° C. for 2 hours and at 50° C. for 5 hours. The precipitate was filtered off and washed with ethanol until the residue was only pale yellowish and then with water until neutral. 33.6 g of 3-(p-diethylaminophenyl) -1,5-diphenylpentane-1,5-dione were obtained. The almost colorless crystals melt at 110° C.
