Phenylacetyl chloride → HCID 54479352, compound

Participants

Reaction Steps

To a solution of 0.387 g of (3S,4S)-4-acetoxy-3-amino-1-t-butyldimethylsilyl-2-oxoazetidine in 20 ml of THF is added 0.24 g of triethylamine under ice-cooling, and then, a solution of 0.32 g of phenylacetyl chloride in THF is added dropwise. The mixture is stirred under ice-cooling for one hour, the insolubles are filtered off, and the filtrate is concentrated under reduced pressure. Purifying the residue on a silica gel column (ethyl acetate:n-hexane-1:2) yields 0.511 g of (3S,4S)-4-acetoxy-1-t-butyldimethylsilyl-3-phenylacetamido-2-oxoazetidine.
