Product 1

HCID 543411833-(Acetylthio)-2-(methylthio)propionic acid chloride

Procedure

The 3-(acetylthio)-2-(methylthio)propionic acid is refluxed in thionyl chloride for two hours. The reaction mixture is distilled to remove excess thionyl chloride and the product is distilled in vacuo to yield 3-(acetylthio)-2-(methylthio)propionic acid chloride.

Workup

  1. distillationThe reaction mixture is distilled
  2. customto remove excess thionyl chloride
  3. distillationthe product is distilled in vacuo
