Reaction Steps
Piperonal (0.63 g, 4.22 mmol), ethanol (4 ml), and aniline (0.38 g, 4.22 mmol) were put in a 25 ml flask, and acetic acid (10 ml) was slowly added dropwise thereto while the mixture was stirred under nitrogen charging conditions, followed by stirring at 80° C. for 12 hours. Then, the temperature of the mixture was lowered to 0° C., followed by the addition of a little water to obtain a solid. The filtering was performed while the solid was washed with cool ethanol, thereby giving clean E)-N-(benz[d][1,3]dioxol-5-ylmethylene)aniline (LJ-2477) with a yield of 45%.
