Reaction Steps
In a stream of argon, to 40 ml of tetrahydrofuran was added 8.0 g of phenyllithium (19% solution in dibutylether) (18.1 mmol). To this mixture, 3.81 g (8.2 mmol) of 4-(hydroxymethyl)benzyltriphenylphosphonium bromide was added under cooling. After the mixture was stirred at the same temperature, 2.0 g (8.6 mmol) of 4-(dibutylamino)benzaldehyde was added thereto. The mixture was stirred at the same temperature for 1 hour. After the reaction mixture was added to water, extraction with toluene, washing with a saturated saline solution, and drying over anhydrous sodium sulfate were performed. Toluene was evaporated off. The residue was purified by silica gel column chromatography to give 2.37 g of a yellow liquid (yield: 85.5%).
