反応手順
Into a n-butanol suspension containing 37 mmol (9.0 g) of 2-methylbutyl p-toluenesulfonate prepared by tosylating S-(-)-2-methylbutanol and 74 mmol (8.2 g) of hydroquinone, added dropwise was a solution of 50 mmol (2.1 g) of sodium hydroxide dissolved in a solvent mixture of 3 ml of water and 10 ml of n-butanol. After conclusion of the dropping, the mixture was then stirred for 8 hours at 120° C. After addition of water, the reaction solution was extracted with ether, and the extracted solution was dried and concentrated. The concentrate was purified by column chromatography, to obtain 4.8 g of the objective ether compound. (Yield: 72%)
