反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-(2-benzyloxyphenoxy)ethanol (3.07 g, 12.6 mmol) and triethylamine (2.63 ml, 18.8 mmol) in chloroform (30 ml) was added methanesulfonyl chloride (1.12 ml, 14.4 mmol) under ice-cooling, and the mixture was stirred for 2 hr. Saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure. Hexane was added to the obtained residue and the precipitated solid was collected by filtration and washed with hexane. The obtained solid was dried in vacuo to give 2-(2-benzyloxyphenoxy)ethyl methanesulfonate (3.77 g, yield 93%). cooling the mixture was extracted with ethyl acetate The organic layer was washed with saturated brine dried over anhydrous magnesium sulfate After filtration the solvent was evaporated under reduced pressure Hexane was added to the obtained residue the precipitated solid was collected by filtration washed with hexane The obtained solid was dried in vacuo

実験手順: To a solution of 2-[2-(2-benzyloxyphenoxy)ethoxy]tetrahydropyran (4.90 g) in tetrahydrofuran (25 ml) and methanol (25 ml) was added 6N hydrochloric acid (15 ml), and the mixture was stirred at room temperature for 1 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed successively with saturated aqueous sodium hydrogen carbonate solution and saturated brine and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel chromatography (hexane:ethyl acetate=1:1) to give 2-(2-benzyloxyphenoxy)ethanol (3.07 g, yield 84%). the mixture was extracted with ethyl acetate The organic layer was washed successively with saturated aqueous sodium hydrogen carbonate solution and saturated brine dried over anhydrous magnesium sulfate After filtration the solvent was evaporated under reduced pressure The obtained residue was purified by silica gel chromatography (hexane:ethyl acetate=1:1)
