Versuchsvorschrift

In a nitrogen atmosphere with cooling with ice, 5.29 mL of 3′-bromoacetophenone was added to 25 mL of 2 M methylmagnesium iodide/diethyl ether solution and 100 mL of diethyl ether, and stirred for 20 minutes. Water and 2 N hydrochloric acid were added to the reaction liquid, extracted with ethyl acetate, washed with aqueous saturated sodium hydrogencarbonate solution and saturated saline water, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure to obtain crude 2-(3-bromophenyl)propan-2-ol.
