الإجراء التجريبي

342 mg of squaric acid) and 2 g of 2-(methyl(3-acetaminophenyl)amino)ethan-1-ol were put in a 100 mL 3-neck rounded bottom flask, and 40 mL of n-BuOH and 20 mL of toluene were added thereto. The mixture was heated and refluxed at 120° C. for 10 hours. Then, a Dean-Stark trap set was used to remove water generated from the reactant during the reaction, and the reactant kept being reacted. When the reaction was complete, the reactant was cooled down, producing crystals. The crystals were filtered, several times cleaned with hexane, and once more recrystallized, obtaining a desired compound.
