反応手順
15.0 g of 2-thiopheneethanol was dissolved in 350 mL of dichloromethane, and 30.2 g of diisopropylamine was added thereto. The resulting mixture was cooled to 0° C. and 17.5 g of 2-methoxyethoxymethyl chloride was added thereto. The resulting mixture was stirred for 2 hours and heated to reflux for 2 hours. The reaction product solution was cooled and concentrated by evaporation under reduced pressure. To the residue, 200 mL of water and 250 mL of n-hexane were added, and the resulting mixture was stirred for 5 minutes. Aqueous layer was discarded, and the organic layer was washed twice with 700 mL portions of water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to obtain 21.5 g (yield of 85%) of the title compound as a colorless oil.
