Reaction Steps

In a stream of argon, to 15 ml of tetrahydrofuran was added 1.68 g of phenyllithium (19% solution in dibutylether) (3.8 mmol), and 1.37 g (3.5 mmol) of 2-thenyl triphenylphosphonium chloride was added thereto under ice cooling. Next, 1.0 g (3.5 mmol) of 3-(4-dibutylamino-2-methoxyphenyl)propenal was dissolved in tetrahydrofuran and added dropwise. The mixture was stirred under ice cooling for 2 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 0.92 g of an orange oily matter (yield: 72.0%).
