Acetyl chloride → HCID 20533759, compound

Participants

Reaction Steps

Triethylamine (13.3 microliters) was added to a solution in 2 ml of dichloromethane of 3.75 mg of the p-nitrobenzyl 3-(2-hydroxyethylthio)-6-ethyl-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate obtained in Example 44. Then, 6.8 microliters of acetyl chloride was added dropwise to the resulting solution at -10° C. with stirring. At the same temperature, the mixture was stirred for 10 minutes. The reaction mixture was diluted with 10 ml of benzene, and washed three times with 5 ml of a 0.1 M phosphate buffer (pH6.8). The organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to afford a yellow oily product.
