Sodium borohydride → HCID 13091200, compound

Participants

Reaction Steps

(3S,4R)-3-[(1RS)-1-(p-Nitrobenzyloxycarbonyloxy)ethyl]-2-oxo-4-(2-oxoethyl)azetidine (8 mg) was dissolved in methanol (0.8 ml) and sodium borohydride (2 mg) was added at 0° C. The mixture was then stirred for 30 minutes at the same temperature and acetic acid (3 drops) was added. The mixture was evaporated and the residue was dissolved in ethyl acetate, washed with aqueous sodium bicarbonate, and brine, dried over magnesium sulfate and evaporated. The residue was purified by preparative thin layer chromatography (silica gel) developing with benzene: acetone (1:1) to give (3S,4R)-4-(2-hydroxyethyl)-3-[(1RS)-1-(p-nitrobenzyloxycarbonyloxy)-ethyl]-2-oxoazetidine (5 mg).
