Reaktionsschritte

In a 100 ml round-bottom flask, the resultant 4-acetoxybenzoic chloride, 3.10 g (15.1 m mole) of 2-amino-4-octylphenol and 40 ml of dioxane were placed and heated to keep inner temperature 85 to 88.5° C. To the mixture, 5.5 ml of pyridine was added dropwise under stirring, followed by heating and stirring for 20 minutes at 85 to 88.5° C. After the reaction, the reaction mixture was cooled with ice and poured into ca. 200 ml of ice water to precipitate a crystal. The crystal was filtered, washed and recrystallized from methanol to obtain 4.10 g of 2-(4-acetoxybenzoylamino)-4-octylphenol (Yield: 70.8%). ##STR79##
