実験手順

In a stream of argon, to 35 ml of tetrahydrofuran was added 3.33 g of phenyllithium (19% solution in dibutylether) (7.53 mmol), and 4.8 g (6.84 mmol) of 4-(tert-butyldiphenylsiloxymethyl)benzyltriphenylphosphonium bromide was added thereto under ice cooling. Next, 1.8 g (6.838 mmol) of 4-dibutylamino-2-methoxybenzaldehyde was dissolved in tetrahydrofuran and added dropwise. The mixture was stirred for 1.5 hours. After the reaction mixture was poured into water, extraction with ethyl acetate, washing with a saturated saline solution, drying over anhydrous sodium sulfate, and concentration were performed. Ethyl acetate/hexane (5/1) was added to the residue and the precipitate was filtered off. The filtrate was reconcentrated and the residue was purified by silica gel column chromatography to give 3.92 g of a yellow liquid (yield: 94.7%).
