실험 절차

19.6 g of 1,2-phenylenediamine was dissolved in 300 ml of dimethylformamide, to the solution were added 11.3 g of the above-prepared 4-chlorocinnamyl chloride crystals and 12.5 g of potassium carbonate at a room temperature with stirring, and the mixture was stirred for 48 hours under the same condition. After adding water and sodium chloride, the reaction mixture was extracted twice with 1000 ml of chloroform, and the extract was dried over magnesium sulfate and evaporated to remove the solvent under a reduced pressure. Resulting residue was applied to a silica gel column and eluted with hexane/ethyl acetate (3:1), to obtain 12.85 g of the title compound as colorless crystals.
