[4-[2-(4-Dibutylamino-2-methoxyphenyl)vinyl]phenyl]methanol → 4-[2-(4-Dibutylamino-2-methoxyphenyl)vinyl]benzaldehyde

Participants

Reaction Steps

In 60 ml of dichloromethane was dissolved 2.28 g (6.2 mmol) of [4-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]phenyl]methanol, and 10.8 g of active manganese dioxide was added thereto. The mixture was stirred at room temperature for 18 hours. After the reaction mixture was filtrated and concentrated, the residue was dissolved in 170 ml of ether, 80 mg of iodine pieces were added thereto, and the mixture was stirred. The reaction mixture was washed with a 5% sodium bisulfite solution and then with a saturated saline solution, and dried over anhydrous magnesium sulfate. After ether was evaporated off, the residue was purified by silica gel column chromatography to give 1.54 g of an orange oily matter (yield: 67.9%).
