Versuchsvorschrift

A stirred solution of 7.0 grams (0.035 mole) of methyl 4-(2-fluoroethoxy)benzoate and 75 ml of a 1.0 M solution of diisobutylaluminium hydride in hexanes in 75 ml of toluene was heated at 40° C. for three hours. The mixture was cooled and quenched with methanol. This mixture was stirred at room temperature for approximately 18 hours and was filtered through a pad of celite. The filter cake was washed with a small amount of methanol. The combined filtrate was evaporated under reduced pressure to yield 5.0 grams of 2-fluoroethyl 4-hydroxymethylphenyl ether as an oil which slowly solidified.
