Reaction Steps

Under a nitrogen atmosphere, 3-methoxythiophene (5.0 g, 44.8 mmol), 2-butyloctanol (16.7 g, 89.6 mmol), and p-toluenesulfonic acid (850 mg, 4.48 mmol) were dissolved in toluene (40 ml), and refluxing was performed for 15 hours. Then, water was added to the reaction solution. The reaction solution was then extracted with methylene chloride, and an organic layer was washed with a saturated saline solution and water. The organic layer was dried with anhydrous magnesium sulfate, and, after filtration, the solution was distilled off under reduced pressure. By separating and purifying the obtained reaction solution by silica gel column chromatography in which hexane was used as a mobile phase, a target substance was obtained as clear oil (83% yield). 1H-NMR (400 MHZ, CDCl3, TMS) δ 7.17 (dd, J=5.2 Hz, 1.6 Hz, 1 H), 6.76 (d, J=5.2 Hz, 1 H), 6.21 (d, J=1.6 Hz, 1 H), 3.81 (d, J=5.8 Hz, 2 H), 1.25 (m, 17 H), 0.88 (m, 6 H)
