実験手順
23.5 g of 2-(ethyl(4-formylphenyl)amino)ethyl acetate, 4.91 g of cyclohexanone and 150 ml of ethanol were mixed and to this was added an aqueous solution (25 ml) of 2.2 g of sodium hydroxide while stirring at 50° C. This mixture was further stirred for 5 hours. After cooling to room temperature, a precipitate was filtrated, and washed with a small amount of ethanol and water to obtain 41.5 g of 2,6-bis((4-(ethyl(2-hydroxyethyl)amino)phenyl)methylene)cyclohexan-1-one.
