Potassium ethanethioate → HCID 54147731, compound

Participants

Reaction Steps

To a solution of 0.7 g of (3S,4S)-4-acetoxy-3-tritylamino-2-oxoazetidine in 10 ml of methanol is added a solution of 0.25 g of potassium thioacetate in 2 ml of water. The mixture is stirred for 30 minutes at 55°-60° C. Methanol is distilled off under reduced pressure. To the residue is added ethyl acetate, followed by washing with water, drying and concentration under reduced pressure. The residue is purified on a silica-gel column (ethyl acetate:n-hexane=1:1) to give 0.195 g of (3R,4R)-4-acetylthio-3-tritylamino-2-oxoazetidine
