74% | In butan-1-ol; at 120℃; for 2h; | General procedure: 1,3-Indandione (0.19 g, 1.3 mmol) and 4-[bis(4-methoxyphenyl)amino]benzaldehyde (a) (0.4 g 1.43 mmol) were dissolved in 22 mL of butan-1-ol and refluxed for 2 h. Then the mixture was cooled down to the room temperature. The solid precipitate was collected and recrystallized from butan-1-ol to give 0.53 g of red crystals (65percent yield). |

75% | General procedure: In a round bottomed flask, indane-1,3-dione (1 mmol) was dissolvedin pyridine (5 mL) and stirred for 5-10 min. Then substituted benzaldehyde(1 mmol) was added and the reaction mixture was refluxed for1 h at 100 C. The reaction progress was monitored by TLC. Aftercompletion, the reaction mixture was brought to room temperature andthen poured onto ice cold water. The resulting precipitates were filteredand washed thoroughly with hexane. The precipitates were crystallizedfrom methanol. |
