Reaction Steps

In a stream of argon, to 20 ml of tetrahydrofuran was added 2.4 g of phenyllithium (19% solution in dibutylether) (5.43 mmol), and 1.95 g (4.94 mmol) of 2-thenyl triphenylphosphonium chloride was added thereto under ice cooling. Next, 1.3 g (4.94 mmol) of 4-dibutylamino-2-methoxybenzaldehyde was dissolved in tetrahydrofuran and added dropwise. The mixture was stirred under ice cooling 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. The residue was purified by silica gel column chromatography to give 1.51 g of an orange oily matter (yield: 89.2%).
