実験手順

To a suspension of lithium aluminum hydride (0.47 g) in tetrahydrofuran (5 mL) was added dropwise a solution of methyl 4-(2-benzyloxybenzyl)benzoate (2.1 g) in tetrahydrofuran (5 mL) at 0° C., and the mixture was stirred at the same temperature for 1 hour. Ethyl acetate (10 mL) was added to the reaction mixture, and the resulting mixture was stirred for 30 minutes. To the reaction mixture were added water and dilute hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 4-(2-benzyloxybenzyl)benzyl alcohol (1.9 g).
