実験手順

4-Anilinophenyl cinnamate was prepared by adding a solution of 18.2 grams of cinnamoyl chloride in 50 milliliters of benzene to a solution of the sodium salt of 4-anilinophenol which was prepared by dissolving 18.5 grams of 4-anilinophenol in a solution of 4 grams of sodium hydroxide in 100 milliliters of ethanol. The addition was accomplished in 30 minutes and the reaction mixture was stirred for one hour. The mixture was then poured into 150 milliliters of water. The organic layer was separated, washed three times with 10 percent sodium hydroxide solution and once with water, dried over anhydrous sodium sulfate, then allowed to evaporate. The residue was washed with boiling hexane. There was obtained 15.0 grams of product which melted at 116°-118° C.
