80 °C

In 10 ml of anhydrous acetic acid were dissolved 0.8 g (3.04 mmol) of 4-(dibutylamino)-2-methoxybenzaldehyde and 0.73 g (3.01 mmol) of 1,3-bis(dicyanomethylidene)indan. The mixture was stirred with heating at 80° C. for 2 hours. The reaction mixture was poured into 200 ml of water and the precipitate was separated by filtration, washed with water, and dried. The crystal was purified by silica gel column chromatography and washed with methanol to give 1.27 g of a black crystal having a mp of 195-198° C. (yield: 86.4%).
