Benzyl Bromide → HCID 14988923, compound

Participants

Reaction Steps

To a solution of 4-[3-(2-hydroxyethyl)-2-methyloxiranyl]-5-methoxy-6-(morpholinocarbonyloxy)-1-oxaspiro[2,5]octane (14.4 mg) in a mixture of anhydrous tetrahydrofuran (1 ml) and N,N-dimethylformamide (1 ml) was added sodium hydride (60% oil dispersion, 4.7 mg) in one portion under ice cooling. The mixture was stirred for half an hour at the same temperature and benzylbromide (13.3 mg) was added. After sitrred for 2 hours at ambient temperature, the reaction was quenched with water (2 ml) and extracted with diethyl ether (1 ml) three times. The combined organic layers were washed with water, dried, and evaporated in vacuo. The residue was purified by column chromatography on silica gel (diethyl ether/n-hexane =1/1) to give 4-[3-(2-benzyloxyethyl)-2-methyloxiranyl]-5-methoxy-6-(morpholinocarbonyloxy)-1-oxaspiro[2,5]octane (4.8 mg).
