Versuchsvorschrift

1-[3-(Benzyloxy)phenoxy]acetone (1.77 g) was dissolved in THF (20 mL), and, a solution of 0.97M methyl magnesium bromide in THF (9.0 mL) was added dropwise thereto with cooling in an ice bath under nitrogen flow. The reaction mixture was stirred at room temperature for 2.5 hours. A saturated aqueous ammonium chloride solution was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with a 1M aqueous sodium hydroxide solution and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=100/0-85/15) to obtain 1-[3-(benzyloxy)phenoxy]-2-methylpropan-2-ol (997 mg).
