Benzyl Bromide → 5-Benzyloxyadamantan-2-one

関与物質

反応手順

To a solution of 4-oxoadamantan-1-ol (5.0 g) in N,N-dimethylformamide (50 ml), sodium hydride (60%, 1.4 g) and benzyl bromide (3.9 ml) were added under ice cooling. The reaction mixture was then warmed to room temperature and stirred for 1 hour. The reaction mixture was diluted with saturated aqueous ammonium chloride under ice cooling and extracted with ethyl acetate. The extracted organic layer was washed with brine, dried over anhydrous magnesium sulfate and then filtered to remove the desiccant, followed by distilling off the solvent under reduced pressure to give 5-benzyloxyadamantan-2-one (8g) as a colorless oil.
