反応手順
24.83 g (0.2 mole) of o-methoxyphenol and 100 ml of tetrahydrofuran were placed in a 500 ml-flask equipped with a stirring device and a cooling pipe. A solution in which sodium methoxide (0.2 mole) was dissolved in methanol was added to the flask while stirring the contents. Then tetrahydrofuran and methanol were eliminated at reduced pressure. 300 ml of tetrahydrofuran was added to the flask and then 46.94 g (0.2 mole) of 2-chloroethyl-p-toluene sulfonate was added thereto. The mixture was then stirred under heating reflux for 20 hours to promote reaction. After reaction, insoluble matters were eliminated by filtration, and the product was condensed at reduced pressure. The reaction mixture was then refined by column chromatography using silica gel, and 25.1 g of 2-(o-methoxyphenoxy)ethyl chloride was produced.
